Conformal cooling is an alternative to conventional cooling where 3D printed moulds have cooling channels shaped in the same outline as the cavity. The heat flux and the interface temperature have been identified using a conjugate heat transfer 3-D CFD model. The model is developed based on steady conditions which are validated using experimental data. A methodology on how to achieve a uniform cooling of a mould of a complex geometry has been presented. A generic equation has then been developed using multiple linear regression method to calculate the interface temperature and its standard deviation as a function of the main parameters which include depth, pitch, diameter and coolant flow velocity. The equation can be used as a guide for cooling channel design without a need for running multiple CFD simulations.
