Techno-Economic Evaluation of Rooftop Photovoltaic Systems in the Indian Context
Problems of greenhouse effect and depletion of conventional resources in the last two decades have resulted in a worldwide exponentially growing photovoltaic market for renewable power generation. The Indian government has ... -
Theoretical And Experimental Studies Of Capillary Pumped Loop And Loop Heat Pipe
(2010-07-13)Capillary pumped loop (CPL) and loop heat pipe (LHP), are two-phase heat transport devices which rely on surface tension induced by a fine pore wick to drive a working fluid in a loop. These are based on a working principle ... -
Thermal Performance of Various Roof Elements Under Different Weather Conditions
(2018-05-14)Beside the point of whether the country is developed or underdeveloped, energy crisis is a common scene all over the world. In order to balance energy supply and demand, either one has to increase the supply or decrease ... -
Thermal Turbomachinery Design for Closed Thermal Cycles and Multiple Fluids
Closed-cycle gas turbines can complement conventional power conversion systems due to their potential for improved efficiencies, compact system layouts, and the ability to exploit non-fossil fuel energy sources which leads ... -
Thermodynamic Analysis And Simulation Of A Solar Thermal Power System
