Abstract

Transient conduction in a rotating cylindrical shell exposed to an incident time varying heat flux D. Eriksson & B. Sunden Division of Heat Transfer, Lund Institute of ABSTRACT The transient temperature distribution in a rotating cylindrical shell, heated by an incident time varying heat flux, is determined numerically. The shell is cooled by combined convection and thermal radiation. The influence of cooling and rotation on the temperature distribution as well as the time- and space- dependence are shown. Rotation provides a sinusoidal temperature variation in time for a given surface and circumferential position. INTRODUCTION Transient heat conduction in a solid with convective or radiative cooling at the surface occurs frequently in real world applications. With the space adventure in the sixties a number of papers were published concerning interplanetary conditions. One of the more related to this paper is that of Olmstead et al. [1] where analytical solutions of the
