The present study aims to establish the optimal performance parameters for the maximum exergy delivery during the collection of solar energy in a flat-plate solar air heater. The procedure to determine optimum aspect ratio (length to width ratio of the absorber plate) and optimum duct depth (the...

In this paper, the design of a triangular built-in storage-type solar water heater with transparent insulation on the top and sides is studied under various operating conditions. The transient performance of the system is studied by using a finite-difference forward time-step marching technique....

We have considered the general case of a collector with four reflectors. An analytical model is developed for study of the effect of an individual reflector on the collector. Reflectors R-1, R-2, R-3, and R-4 face south, north, west, and east, respectively. For a collector with two reflectors...

Energetic and exergetic analysis has been carried out for the components of the solar thermal power plant system (parabolic trough collector/receiver and Rankine heat engine). The energetic and exergetic losses as well as efficiencies for typical parabolic trough concentrating solar thermal...

A framework for financial evaluation of a box-type solar cooker, using cost functions for its capital cost, has been developed. The annual benefits accrued to the user are quantified in terms of number of meals cooked per year and monetary worth of the fuel saved per meal. Expressions for some...
