Abstract
Solar energy storage system finds an application in cooking areas in domestic life especially in the hilly regions of INDIA. For this purpose packed bed system has a better acceptability. Utilization of packed-beds with bed elements with geometrical shapes and sizes and types of rocks and ducts resulted in temperature stratification with an aim to improve the efficiency of solar heater with air as the medium has been proposed by various investigators. However the increase in efficiency also leads to pressure loss; therfoere the system should be robust and designed in such a manner in order to accomodate minimum pressure loss. Pressure losses are generally the function of Reynolds number. (Re., Sphericity (ψ), Void fraction (ϵ), Equivalent diameter (De). So in this work optimization of the solar energy storage system has been performed by considering different shapes and a novel design is proposed. The effect of sphericity over the volumetric heat coefficient and pressure losses is also analysed.
