Abstract
An asymptotic and numerical investigation was conducted for the cooling process, by a forced laminar flow, of a small strip with a non-uniform heat source. The nondimensional temperature distribution in the strip has been obtained as a function of the following parameters: (a) the intensity and distribution of the internal heat sources, (b) the aspect ratio of the strip, (c) the longitudinal heat conductance of the strip and (d) the Prandtl number of the fluid. Both the thermally thin as the thick wall approximations were considered in this paper. The total thermal energy or averaged temperature of the strip is found to decrease as the influence of the longitudinal heat conduction effects in the strip decreases in the thermally thin wall regime. After reaching a minimum, it increases again in the thermally thick wall regime.
