Abstract

The need for energy and its utilization for industrial, house-hold purposes has seen an ever increasing hike. However, the uncontrolled and excessive usage of conventional energy resources, like burning fossil fuels has been deteriorating the environment and thereby causing health related issues. Flat-plate solar collector is one of the most promising system to utilize solar energy to fulfil the thermal or heating requirements. An effective design of a flat-plate solar collector requires numerous factors to be considered such as riser tube material and its configuration, absorber plate material, glazing material etc. In the present work, the scope of the study is to analyse the effect of glazing material on the thermal and hydraulic performance of the collector. For this purpose, five different types of materials have been selected in a typical generalized computer-aided module of a riser configuration for a flat-plate solar collector and each material has been examined for its performance with different mass flow rates of working fluids. Computational fluid dynamics (CFD) has been instrumental in studying the influence of the glazing materials.
