Abstract. The manufacture of composite parts is a complex process, where the final quality of the part depends on several parameters, one of which is crucial: thermal management during the manufacturing process. Whatever the process, thermal management must be carried out with accuracy. Traditional management with circular channels, whether optimized or not, has its limits in terms of efficiency and temperature uniformity, particularly for complex geometries. To overcome these limitations, the use of porous media, and lattice structures in particular, is an alternative for improving uniformity and efficiency. This system, in which the cooling fluid circulates in the lattice structure, is studied in this work in order to analyze heat transfer and fluid dynamics locally, and to demonstrate the feasibility of the system.
