The conjugate heat transfer from an internal heated small strip in a forced laminar flow

An asymptotic and numerical investigation was conducted for the cooling pro cess, by a forced laminar flow, of a small strip with a non-uniform heat so urce. The nondimensional temperature distribution in the strip has been obt ained as a function of the following parameters: (a) the intensity and dist ribution of the internal heat sources, (b) the aspect ratio of the strip, ( c) the longitudinal heat conductance of the strip and (d) the Prandtl numbe r of the fluid. Both the thermally thin as the thick wall approximations we re considered in this paper. The total thermal energy or averaged temperatu re of the strip is found to decrease as the influence of the longitudinal h eat conduction effects in the strip decreases in the thermally thin wall re gime. After reaching a minimum, it increases again in the thermally thick w all regime.
