ABSTRACT

Based on the energy equation formulation, a numerical simulation for characterizing the transient heat exchange between a steady laminar boundary layer and a flat sample is established. The unsteady behaviour is developed after generation of an impulsive heat flux step on the upper face of the plate. Two cases are considered according as the plate has a finite thickness or without thickness. The time and space evolution of both the surface temperature and the heat exchange coefficient is evidenced. The results are compared to the steady solution deduced from the KARMAN-POLHAUSEN method.
