Abstract

This method for determining the thermal performance of a heat exchanger comprising channels delimited by welded inner and outer skins and through which a fluid circulates includes: - finite element discretization of the outer skin; - determination of a temperature evolution function between the channels; - determination of an average heat exchanger temperature between the channels by applying a discretized integral method; - determination of the temperature of the inner skin forming an inner wall of the channels; - determination of an aerodynamic skin equation for the outer skin by applying a finite difference method; - determination of the total power dissipated by the heat exchanger; - determination of the thermal performance of the heat exchanger.
