Title: Feasible thermophysical conditions for gas receiver tubes in solar power stations
Abstract: Heat transfer to air in turbulent pipe flow is analyzed and numerically computed. This is applied to estimate the energy transfer process in a solar thermal receiver of a central tower facility. The general condition of uniformly heated pipe flow will be discussed with dependence on, e.g., heat flux (10 to 1000 kW/m-sq), inlet pressure (4 to 80 bar), and tube radius (10 to 40 mm). For technical and economical optimization, the combination of high heat flux and high pressure is recommended. Thus, for a solar power station with gas as heat transfer medium, the closed thermal cycle is favored.
