The high-lift performance of an aircraft largely effects it’s economic viability. An effective high-lift capacity of aircraft allows greater payloads, less fuel consumption and longer range for given gross weight. Generation of increased lift also allows steeper take-off ascent which can reduce the required size of runway. Mechanically simple high-lift devices are easier to manufacture and minimize manufacturing and maintenance costs, thus increasing profitability. Gurney flap is one such mechanically simple high-lift device. A Gurney flap is a flat plate of the order of ‘some small percentage’ of the aerofoil chord in length, generally oriented at right angle to the chord line of the aerofoil. The two-dimensional aerodynamic performance of the Gurney flap is characterized by means of computational fluid dynamics. Simulations are carried out on a NACA 4412 airfoil equipped with Gurney flap and effects of flap size, mounting angle and mounting position on airfoil performance are investigated. This author recommends that a Gurney flap of 2% chord length should be installed at the trailing edge perpendicular to the chord of the airfoil. © 2017, American Institute of Aeronautics and Astronautics Inc, AIAA.

Electroanalysis | Year: 2012

A new ionophore, i.e. p-(2-thiazolazo)calix[4]arene (I) has been explored for its selective behavior towards Ni(II) ions. A poly(vinyl chloride) based membrane containing (I) as an electroactive material along with sodiumtetraphenylborate (NaTPB), and nitrophenyloctyl ether in the ratio 10:100:3:150 (I:PVC:NaTPB:NPOE) (w/w) was used to fabricate an all solid state nickel(II)-selective sensor. The developed sensor exhibited a working concentration range of 1.0×10 -6-1.0×10 -1M, with a Nernstian slope of 28.9±1.0mV/decade of activity and a response time of 10-15s. This sensor shows a detection limit of 9.0×10 -7M. Its potential response remains unaffected of pH in the range 3.0-7.6, and the cell assembly could be used successfully in partially nonaqueous medium (up to 10% v/v) without any significant change in the slope value or the working concentration range. The sensor worked satisfactorily for about ten weeks and exhibited excellent selectivity over a number of mono-, bi-, and tri-valent cations including alkali, alkaline earth metal, and transition metal ions. It could be used as an indicator electrode for the end point determination in the potentiometric titration of nickel ions against ethylenediaminetetraacetic acid (EDTA) as well as for the determination of nickel ion concentration in real samples. © 2012 WILEY-VCH Verlag GmbH & Co.

Physics of Plasmas | Year: 2014

We study the linear analysis of electrohydrodynamic capillary instability of the interface between two viscous, incompressible and electrically conducting fluids in a fully saturated porous medium, when the phases are enclosed between two horizontal cylindrical surfaces coaxial with the interface and, when there is mass and heat transfer across the interface. The fluids are subjected to a constant electric field in the axial direction. Here, we use an irrotational theory in which the motion and pressure are irrotational and the viscosity enters through the jump in the viscous normal stress in the normal stress balance at the interface. A quadratic dispersion relation that accounts for the growth of axisymmetric waves is obtained and stability criterion is given in terms of a critical value of wave number as well as electric field. It is observed that heat transfer has stabilizing effect on the stability of the considered system while medium porosity destabilizes the interface. The axial electric field has dual effect on the stability analysis. © 2014 AIP Publishing LLC.

We study the linear magnetohydrodynamic Kelvin-Helmholtz instability of the interface between two viscous, incompressible, and electrically conducting fluids. The phases are enclosed between two coaxial cylindrical porous layers with the interface through which mass and heat transfer takes place. The fluids are subjected to a constant magnetic field parallel to the streaming direction, and the suction/injection velocities for the fluids at the permeable boundaries are also taken into account. Here, we use an irrotational theory in which the motion and pressure are irrotational, and the viscosity enters through the jump in the viscous normal stress in the normal stress balance at the interface. We consider both asymmetric and axisymmetric disturbances in our analysis. A quadratic dispersion relation is deduced and stability criterion is given in terms of a critical value of relative velocity, as well as, magnetic field. It has been observed that in the case of permeable boundaries, heat and mass transfer phenomena play a dual in the stability analysis. The flow through porous medium is more stable than the pure flow. © 2014 AIP Publishing LLC.

Renewable and Sustainable Energy Reviews | Year: 2013

India's power generation capacity needs to be augmented to, support the growing demands for electricity. India, which has predominantly used fossil fuels to power its generators need to make a switch to clean energy fuels. But renewable sources form a miniscule portion (26 GW,~12%) of India's overall installed power capacity (210 GW). There is no contribution from offshore wind farms to the energy basket for India, as there is no policy framework to encourage the development of offshore wind farms. Several European countries have tapped the offshore wind energy potential to reduce their dependence on adopted by these countries to identify the core components (21 of them) of robust policy intervention. A detailed questionnaire was administered to 181 stakeholders of wind energy in India to seek their feedback on these building blocks. These core components (variables in research parlance) are then subjected to factor analysis to understand the underlying structure of the variables. The factor analysis logically reduces these 21 variables into five factors (Government support, fiscal and quota based incentives, availability of local expertise, capital for investments and building an enabling R&D ecosystem), which are then fed into a logistic regression model as 'independent variables' to predict the probability of growth of offshore wind energy (dependent variable) in the country. The logistic regression model gives the weight (the impact) of these independent variables in influencing the growth of offshore wind energy in India. It emerges that government support, fiscal and quota based incentives and building an enabling R&D ecosystem have a much higher impact on the growth of offshore wind energy for India. This paper fills the gap of absence of an empirically tested framework on offshore wind energy policy for India. © 2013 Elsevier Ltd.

Energy Policy | Year: 2013

Indian Economy is growing at a healthy pace during the last few years. To sustain this growth, power sector needs to build additional generation capacity. However, continued dependence on fossil fuels to power the growth of electricity generation capacity, is hardly sustainable. Renewable Energy source forms a miniscule portion (25. GW,~12%) of India's overall power generation today (202. GW). The share of wind energy (17. GW) is 67% of the total renewable energy basket. But the contribution from offshore wind farms is non-existent, as all the wind energy generated in India is only through onshore wind farms. India needs a policy framework to encourage the development of offshore wind farms. Several European countries have effective offshore wind energy policies that have helped them to accelerate the growth of their offshore wind energy sector. This paper does an exhaustive literature survey, to identify 21 building blocks of a successful offshore wind energy policy initiative adopted by select European countries, which have been classified under 5 broad categories-Government support, Fiscal and quota based incentives, Availability of local expertise, Capital for investments and Building an enabling ecosystem, which can be leveraged by India to articulate its own offshore wind energy policy. © 2013 Elsevier Ltd.

Microalgae are receiving increasing attention worldwide as an alternative and renewable source for energy production. Through various conversion processes, microalgae can be used to produce many different kinds of biofuels, which include biodiesel, bio-syngas, bio-oil, bio-ethanol, and bio-hydrogen. However, large scale production of microalgal biofuels, via many available conversion techniques, faces a number of technical challenges which have made the current growth and development of the algal biofuel industry economically unviable. Therefore, in addition to algae culture and growth, it is also essential to develop cost-effective technologies for efficient biomass harvesting, lipid extraction and biofuels production. This review aims to collate and present an overview of current harvesting, oil extraction and biofuels production technologies from microalgae. Since much of the current studies on oil extraction are focused on biodiesel production from microalga, this study, apart from discussing the various biodiesel production techniques in the later sections, has also done a detailed discussion on the production techniques of other biofuels. © 2013 Elsevier Ltd.

In this report, using finite difference time domain simulation, a highly sensitive H-shape subwavelength plasmonic metasurface is demonstrated for refractive index sensor at near-infrared wavelengths. Numerical simulations show that optical transmission and reflection properties of such H-shape slit metamaterial depend significantly on the refractive index of the surrounding medium. The studies reveal that an index change of 0.5 results in a resonant frequency shift of nearly 600 nm, which is about 1200 nm shift per refractive index unit (RIU). The detection accuracy of ∼0.0035 RI for every 5 nm resonance frequency shift can be achieved. The frequency shift is explained on the basis of inductor capacitor (LC) model of the H-unit. © 2014, Springer Science+Business Media New York.

We study the linear analysis of capillary instability of a cylindrical interface between two viscous and dielectric fluids, when the fluids are subjected to a constant axial electric field and, when there is heat and mass transfer across the interface. We use viscous correction for the viscous potential flow theory in which the discontinuities in the irrotational tangential velocity and shear stress are eliminated in the global energy balance by taking viscous contributions to the irrotational pressure. A quadratic dispersion relation that accounts for the growth of axisymmetric waves is obtained and stability criterion is given in terms of a critical value of wave number as well as electric field. It is observed that heat transfer and electric field both have stabilizing effect while vapor fraction has destabilizing effect on the stability of the system. © 2013 Production and hosting by Elsevier B.V. on behalf of Ain Shams University.

The effect of heat and mass transfer on the Kelvin-Helmholtz instability between liquid and vapor phases of a fluid has been studied using three different theories: a purely irrotational theory based on the dissipation method, a hybrid irrotational-rotational theory, and an inviscid potential flow theory. These new results are compared with previous results from viscous irrotational theory. The stability criterion is given in terms of the critical value of relative velocity. The system is shown to be unstable when the relative velocity is greater than the critical value of relative velocity; otherwise, it is stable. It is observed that heat and mass transfer has a destabilizing effect on the stability of the system while vapor fraction has a stabilizing effect. Copyright © 2014 by ASME.
