Parabolic trough solar technology is the most widely used and lowest cost large scale solar power technology available today. Corrugation is one of the important methods involved in the passive techniques of enhancement. This report provides an evaluation of numerical simulation studies on heat transfer enhancement, in the corrugations specifically in corrugated tubes which includes the turbulent flow regions. The flow and heat transfer characteristics in a symmetric outward convex corrugated tube has been investigated through numerical simulations based on the Reynolds stress transport (RST) model. In this report validation of the obtained results of RST modeling and the existing results of RST modeling simulation by Feng-Chen Li has been carried out. The simulation results, including velocity and temperature distributions for different profiles between carried out and existing simulation match well. On this basis, the same procedure of RST modeling simulation is applied to research the detailed flow and heat transfer mechanism in proposed corrugated receiver tube model. In one corrugation of the model, detailed study of mean velocity, mean temperature and Reynolds stress at different profiles is carried out. It is found that, in the proposed model of corrugation structure the velocity fluctuation intensity greatly increases, as a result of that there is increase in heat transfer rate which leads to increase in the efficiency of thermal power plant application.
