The flow pattern and attributes of heat transfer in symmetric outward curved layered corrugated tube has been researched based on Reynolds stress transport (RST) model using numerical simulations. In this study validation of obtained RST modelling results and existing RST modelling results of simulation by Feng-Chen Li has been carried out and results mate well. Based on this, same procedure of RST modelling simulation is applied to investigate detailed pattern of flow and mechanism of heat transfer in proposed model of corrugated receiver tube. In one corrugation of the model, detailed study of velocity, temperature and Reynolds stress distribution for various profiles is done. It is determined that, in proposed model of corrugated receiver tube structure intensity of velocity fluctuation greatly increases, as a result of that there is rise in rate of heat transfer which leads to raise in efficiency of thermal power plant application.
