摘要

The solar energy option has been identified as one of the promising alternative clean source for future. Investigation of heat loss from receiver and Heat transfer from the receiver to the working fluid are very important in determining the performance of solar parabolic trough collector. In the present study the concepts of engineering, physics, energy, economy etc. are going to be used. In this study numerical Model is being formulated for the receiver for internal heat gain characteristics and heat loss due to Natural convection as studied by Ravikumar and Reddy. but in the present study spiral receiver geometry is designed for analysis. The internal flow and heat transfer analysis is being carried out on a RNG. k-ε turbulent model whereas external heat losses are treated as Laminar conventional model. The Numerical model is being solved using commercial engineering package Fluent 6.2. The thermal analysis of receiver is being carried out for various geometrical parameters such as angle, orientation, aspect ratio, height of receiver, heat flux conditions with working fluids (heat transfer fluids which are not analyzed by other researcher). Also the thermal analysis of various receiver geometries (which are different and not analyzed by other researcher) are being considered for the evaluation of solar parabolic trough concentrator.
