Present paper deals with the study for performance evaluation of steam-injected gas turbine (STIG) based power plant with inlet evaporative cooling. It investigates the combined effect of inlet evaporative cooling (IEC), steam injection (SI) and film cooling (FC) on the power augmentation of simple gas turbine cycle. Thermodynamic modeling has been carried out and presented along with results showing the influence of inlet evaporative cooling on various performance parameters of STIG based power plant. Results show that there occurs increment of 3.2% in cycle thermal efficiency due to lowering of the compressor inlet temperature from 318 K to 282 K at 5% steam to air ratio (SAR). At 1850 K turbine inlet temperature and cycle pressure ratio of 24 there occurs increase in thermal efficiency of the GT cycle with IEC, SI and FC as compared to the simple GT cycle. Injection of steam in the combustion chamber enhances the specific expansion work in the gas turbine, which increases at rate of 2.95% for every increase in SAR by 2%. The study shows that gas turbine cycle configuration with inlet evaporative cooling (IEC), steam injection and film cooling is the best combination for obtaining more efficiency and power. © 2016 Elsevier Ltd.

Ammonium formate in presence of palladium-carbon is an efficient system for catalytic transfer hydrogenation of several functional groups under mild conditions. However, this system was not found effective for reduction of quinones to hydroquinones, although reduction could be effected with phosphinic acid, phosphinates or cyclohexene as donors. A reexamination of this reaction suggested that formates were good hydrogen donors in this reduction but the reaction was inhibited due to quinhydrone formation. A simple expedient of maintaining low concentration of quinone during catalytic transfer hydrogenation reduction gave excellent yields of the hydroquinone. Compared to formates, formic acid was found to be a poor hydrogen donor.

Abstract The growing trends in wind energy technology are motivating the researchers to work in this area with the aim towards the optimization of the energy extraction from the wind and the injection of the quality power into the grid. Over the last few years, wind generators based on permanent magnet synchronous machines (PMSMs) are becoming the most popular solution for the modern wind energy conversion systems (WECSs). This paper presents a concise review of the grid-integrated WECSs employing permanent magnet synchronous generators (PMSGs). It reviews the trends in converter topologies, control methodologies, and methods for maximum energy extraction in PMSG based WECSs, which have been reported in various research literatures primarily in reputed research journals and transactions during last few years. It also presents an overview to the grid interconnection issues related to output power smoothing and reactive power control in addition to fault-ride-through (FRT) and grid support capabilities of PMSG based WECSs. This review article will serve the researchers working in the area of grid-integrated PMSG based WECSs in the exploration of trends, developments and challenges in the past research works and in finding out the relevant references for their research work. © 2015 Elsevier Ltd.

An ac-to-ac converter has been developed to convert the variable input frequency in wind energy conversion system (WECS) to a constant output frequency of 50 Hz for a distributed generation unit. The switching strategy and control mechanism for the converter is presented using time domain simulations in MATLAB environment. A specific triggering pattern has been generated for the switching devices in the converter to achieve desired polarity of the output voltage across the distributed load. The harmonics in the input supply side of the converter are mitigated by using delta modulation technique, whereas in the output of the converter, passive filtering has been used along with delta modulation technique. The design and implementation issues of the modulation technique and the switching scheme are discussed in detail with suitable simulation and experimental results. The analysis and properties of the proposed solution is compared with the known solutions. It has been concluded that an ac-ac converter is technically a viable option to interface a wind turbine to a utility grid. 1551-3203 © 2015 IEEE.

Thin films of CdS0.5Se0.5 have been deposited on ultra-clean glass substrates by screen-printing method followed by sintering process. Cadmium sulphide, cadmium selenide and cadmium chloride have been used as the basic source material. Optimum conditions for preparing good quality screen-printed films have been found. X-ray diffraction studies revealed that the films are polycrystalline in nature, exhibiting wurtzite (hexagonal) structure with strong preferential orientation of grains along the (0 0 2) direction. The optical band gap of the films has been studied using reflection spectra in wavelength range 350-900 nm by using double beam spectrophotometer. The electrical resistivity of the films was measured in vacuum by two probe technique. © 2012 Elsevier GmbH.

Closed form expressions for the low cycle and high cycle fatigue crack growth lives have been derived for the randomly-planar oriented short-fiber reinforced metal matrix composites under the total strain-controlled conditions. The modeling was based on fatigue-fracture mechanics theory under both the small scale and the large scale yielding conditions. The modified shear lag theory was considered to describe the effect of yielding strength. The present model is essentially a crack growth model because crack initiation period in short fiber reinforced metal matrix composite is much shorter; hence, not assumed to play a dominant role in the calculation of fatigue crack growth life. The effects of short-fiber volume fraction (Vf), cyclic strain hardening exponent (n′) and cyclic strain hardening coefficient (K′) on the fatigue crack propagation life are analyzed for aluminum based SFMMCs at different levels of cyclic plastic strain values. It is observed that the influence of fatigue crack growth resistance increases with increase in cyclic strain hardening exponent (n′) and decreases when volume fraction (Vf) or cyclic strain hardening coefficient (K′) increases. The present MSL theory based fatigue crack growth life prediction model is an alternative of modified rule of mixture and strengthening factor models. The predicted fatigue life for SFMMC shows good agreement with the experimental data for the low cycle and high cycle fatigue applications. © 2014 Elsevier Ltd. All rights reserved.

In restructured electricity markets, forecasting electricity parameters are most essential tasks & basis for any decision making. Forecasting price in competitive electricity markets is difficult for consumers and producers in order to plan their operations and to manage their price risk, and it also plays a key role in the economic optimization of the deregulated power industry. Accurate, short-term price forecasting is an essential instrument which provides crucial information for power producers and consumers to develop accurate bidding strategies in order to maximize their profit. In this paper artificial intelligence (AI) has been applied in short-term price forecasting that is, the one hour ahead price forecast of the electricity market. A new artificial neural network (ANN) has been used to compute the forecasted price in Ontario electricity market using MATLAB R13b. The data used in the forecasting are hourly historical data of the electricity load and price of Ontario electricity market. The simulation results have shown highly accurate one hour ahead forecasts with very small error in price forecasting. © 2015 IEEE.

Mobile ad hoc networks (MANETs) do not depend on any fixed infrastructure, but communicate in a self-unified way. In order to provide secure communication, researchers are working specifically on the security issues in MANETs, and many secure routing protocols/measures within the networks have been proposed. Our proposed work presents a more efficient approach for detecting the cooperative black hole attack in a MANET, which is particularly vulnerable compared to traditional wired networks due to its mobility and broadcast nature. An opponent can easily deploy black hole attack in the MANETs, therefore, to detect cooperative black hole attack, our mechanism modifies the Ad hoc On Demand Distance Vector (AODV) routing protocol by introducing two special packets, (i) query packet and (ii) further route request (FRREQ) packet. Our simulation results show that attack is detected successfully and it outperforms existing attack detection methods. © Springer International Publishing Switzerland 2015.

In this paper a screen-printing method has been employed for the deposition of low zinc content cadmium zinc sulphide (Cd 0.9Zn 0.1S) composite thin films on ultra clean glass substrate. Cadmium sulphide, zinc sulphide and cadmium chloride have been used as the basic source material. With these basic source materials, the optimum conditions for preparing good quality screen-printed films have been found. X-ray diffraction studies revealed that the films are polycrystalline in nature, single phase exhibiting wurtzite (hexagonal) structure with strong preferential orientation of grains along the (1 0 1) direction. SEM/EDAX analysis confirms the formation of ternary compound. The optical band gap (E g) of the films has been studied by using reflection spectra in wavelength range 350-600 nm. The DC conductivity of the films has been measured in vacuum by a two probe technique. © 2011 Elsevier B.V.

The fatigue life prediction model based on crack propagation from micro-structural features is derived and presented for planar and randomly oriented Discontinuous Reinforced Metal Matrix Composites (DRMMCs). The model contains the influence of micro-structural properties such as aspect ratio, volume fraction of particle/fibre and constraint between particle and the matrix. The effect of residual thermal stresses generated within the matrix during development of composite is considered. The particle/fibre plays a dominant role in the development of the cyclic plastic zone size ahead of the crack tip; moreover, it enhances the cyclic plastic deformation characteristics of DRMMC. The theoretical model-based evaluations for low cycle fatigue in DRMMCs are within the proximity of the experimental results. © 2016 Wiley Publishing Ltd.
