Numerical investigation of plate heat exchanger surfaces G. Bigoin', P. Tochon\ J.F. Fourmigue* & J.M. Grilled ^CEA-Grenoble, DTP/GRETh, Grenoble, France. Abstract Plate heat exchangers are more and more used in a wide range of industrial processes due to their high level of heat transfer compared to the volume of the device. It concerns particularly plate-and-frame heat exchangers which have already replaced classical shell-and-tube heat exchangers in many industrial applications, such as air conditioning, chemical, petro-chemical and food industries. Numerous types of corrugation plates are currently available on the market ; but enhancement of heat transfer is still a main concern for manufacturers, whose final goal is to provide heat exchangers with a reduced number of plates ; and consequently, a reduced cost of production. At the moment, this research of new geometries is essentially achieved by means of experimental tools. So, the objective of this paper is to co
