SINOPSIS

A numerical study of transient forced convection in parallel-plate heat exchanger is presented. The walls are insulated and the separating plate has a negligible resistance. The fluids flow is supposed laminar and fully developed. To obtain the transient effect of the heat transfer, a sudden change of the temperature of one or both fluids is imposed at the entrance. A finite difference method is used to solve the problem. The effect of the nature of the fluids, the heat capacity of the separating plate, the magnitude of the flow rate and the temperature step is analysed. A distortion in the temperature profile and some inverse variations of the temperature near the seprating plate are observed in some cases during the transient phase. The duration of the unsteady state depends on the sign of the temperature step.
