Simulation of casting processes is now industrially available with different softwares proposed to foundrymen. Yet, it is always difficult to provide the boundary conditions as correct as possible to represent accurately the environment of the mould. The knowledge of heat transfer coefficient used to modelize the cooling devices in permanent moulds is very important, as well as the acquisition of accurate data regarding die coatings or physical properties. After having conducted a sample survey with French foundries, the experiment conditions have been defined. Two main types of cooling device have been studied: water running in a pipe and air flowing in a special shape to provide localized cooling. Some of the heat transfer coefficients have been simply calculated using Colburn`s law, others have been determined using a 1D or 2D inverse method. Auto-validation results obtained on the experimental device simulated with SIMULOR, a 3D finite volume software, are encouraging.
