Basic Fundamentals of Parabolic Trough Collector

In the present study a fabrication and performance analysis on a close type parabolic trough collector is performed. Different parameters of the system such as receiver tube diameter, material of the receiver tube and heat transfer fluid are chosen for the study and evaluating the performance of the system. In the present work stainless steel with mirror finish is taken as the reflecting material for the trough. Stainless steel and copper are taken as the material for the receiver tubes. The Absorber Tube is fabricated and then painted with black paint in order to increase its absorptivity and reduce losses. Water is used as heat transfer fluid.
