Heat Transfer Behavior of a PTC Receiver Tube Using Transversal Focal Inserts and CFD

In this paper the thermohydraulic performance of an improved Parabolic Trough Collector tube is investigated. Since the absorber tube of the Parabolic Trough Collector is subjected to non-uniform heat flux, and the focal part of the absorber is subjected to a concentrated solar flux, a temperature gradient on the tube circumferential surface is produced. In order to enhance the heat transfer between the Heat Transfer Fluid and the inner surface of the absorber tube and decrease the temperature gradient of the tube’s outer surface and also the temperature of the Heat Transfer Fluid inside the absorber tube, transversal focal inserts are placed on the receiver tube's bottom part as a passive method to increase the mixing of the fluid and decrease the temperature gradient. The geometrical parameter of the inserts as the insert’s height is analyzed and investigated using Finite Volume Method coupling Monte Carlo Ray Tracing method for Reynolds number range from 2.36x104 to 11.83x104. The Therminol®VP1is used as Heat Transfer Fluid in this study. The numerical results show that the enhanced tube by using this kind of inserts increases the thermal performance of the Parabolic Trough Collector system, and also, introducing the inserts into the receiver tube reduces the heat loss to the ambient, decreases the temperature differential across the absorber tube's circumferential region, and increases the receiver's lifespan.
