... of the absorber is subject to a high flux concentration and its upper half is subject to global irradiance. Thus, a nonuniformity in the heat flux distribution on the absorber circumference is observed. Therefore, the heat transfer analysis for the turbulent flow of heat transfer fluid (HTF) inside a parabolic...
