Abstract:

When certain conditions are satisfied, radiative exchange predominates over other modes of heat transport within evacuated arrays of thin parallel plates, concentric cylindrical, or spherical shells. The system of equations which provides the transient temperature of each plate or shell of such an array is displayed. Approximate analytic solutions are presented for small values of time for the case of uniform initial temperature. A steady-state solution is also presented, together with certain numerical results for general values of time. The temperature histories of such arrays may serve to indicate the character of the temperature response of more complex evacuated particulate media in which radiative transport of heat energy predominates. Such a situation may prevail in the case of certain planetary and satellite surfaces. Author
