ABSTRACT
Heat exchangers are important parts of ships’ propulsion systems. Their design and optimization require new simulation methods development in order to improve accuracy on physical model, numerical and computer performances. This article is related to a long-term research project initiated by a large industrial group in collaboration with two academic partners. This collaboration is leading to the development of a global method for heat exchangers’ thermohydraulic simulations.

INTRODUCTION
The industrial uses of digital simulation continue to diversify, benefiting from constant innovation, the fruit of collaborative work between the academic and industrial worlds. The present case study provides an example of this, involving the sizing and optimization of heat exchangers used in the propulsion systems of technological vessels (submarines, aircraft carriers). Improving the performance of these heat exchangers, which are designed to meet stringent operational and functional requirements (compactness, safety, durability, etc.), calls for fast, accurate numerical methods to produce useful data for engineers and designers.
A research program undertaken over almost a decade by a major international shipbuilder, in collaboration with academic researchers with expertise in modeling and simulating complex flows, has led to the development of an innovative calculation method. Validated by comparison with reference results (tests and calculations), the physical and numerical modeling proposed has reached a technological maturity that enables it to be used to meet concrete industrial needs.
