CFD and Experimentation on Heat Transfer Enrichment in Receiver Tube for Parabolic Trough Collector

Abstract

In this work, the CFD simulation of the water flow through the plain circular tube is done, and the constant heat flux is given on the surface of the tube for predicting the Nusselt’s number and friction factor which help in determining the enhancement in heat transfer rate. The results obtained from CFD investigation are compared with the Dittus-Boelter correlations. This will validate the numerical model used here. To perform the CFD analysis first a 3-dimensional geometric model is created, then model is meshed according to the boundary conditions and then simulation is performed.
