The University of Petroleum & Energy Studies is an Indian University located in Dehradun, Uttarakhand known traditionally for its education and research in fields of energy & power.UPES Dehradun, established through an act of the State Legislature of Uttarakhand in the year 2003, is sponsored by Hydrocarbons Education and Research Society. It provides domain specialized programs in oil and gas, transportation, power, computer science, information technology, international business, logistics and supply chain, infrastructure. UPES is the only Asian University to receive the World Oil Award. UPES is an endeavour of Hydrocarbons Education & Research Society , a non profit organization registered under the Societies Act 1860 dedicated to promoting education and training in Energy and allied sectors.The university offers over 75 undergraduate and postgraduate programs.UPES is the one of the first university of India to provide UG, PG and PhD programs in the core sectors of petroleum and energy.UPES is the only university to set up an Oil Rig on campus. The campus is also enabled with 1KW wind turbine mill and a solar power project with 100 KWp installed capacity. It is the first Indian Energy Institution to set up an in-house Bio-Diesel Laboratory. It became a part of the Laureate International Universities network in 2013. Wikipedia.

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.

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. Source

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. Source

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. Source

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.
