Simulation of heat transfer augmentation during constant solar heat flux in circular pipe
Keywords:Nusselt number, solar flux, heat transfer, reynold number
The aim of the current research is to evaluate the flow characteristics and heat transfer enhancement in a circular hose having a diameter of 12.5 mm and 1500 mm Length subjected to a constant solar heat flux of (1000 W/m2) using numerical simulation. The study evolves the changing Reynolds numbers (5000 <Re < 10500) and its effect on the Nusselt number during variable flow rate conditions from 0.45 m/sec to 0.90 m/sec. The heat transfer phenomenon was evaluated during controlled conditions with working fluid as water. The results obtained from numerical investigations were studied to understand the flow and heat transfer enhancement, Nusselt number phenomenon, outlet temperature, and fluid fully developed region.
