The fluid flow and thermal transport associated with a heated plate moving in a uniform forced flow in the same direction as the motion of the plate has been numerically investigated. Two forced flow circumstances, involving a plate moving in a uniform flow in a channel and that in a uniform free stream in an extensive medium, are considered in this study. These circumstances are of interest in a wide variety of manufacturing processes such as continuous casting, extrusion, wire drawing, and fiber drawing. A detailed numerical study is carried out, assuming a two-dimensional, laminar, steady circumstance. The governing elliptic equations are solved, employing finite difference and finite volume methods. The transport in the solid material is coupled with that in the fluid through the boundary conditions and the two are solved for simultaneously. The numerical simulation of such conjugate transport processes is discussed, outlining the important considerations to obtain accurate results for a wide variety of practical problems that involve a moving material subjected to heat transfer. The numerical results for the flow field and the temperature distributions in the solid, as well as in the flow, are obtained. The numerical imposition of the boundary conditions is shown to be a very important aspect in the simulation. The effect of the relevant parameters that arise in the numerical scheme on the results is also determined. The numerical results obtained indicate that the penetration of the conductive effects, upstream of the point of emergence, is significant. When a plate moves in a channel flow, the effect of the channel width on the resulting heat transfer rate is significant, over ranges of practical interest. However, when the channel width increases, the resulting heat transfer in case of a plate moving in a channel flow approaches to those in case of a plate moving in free stream, as expected.
