NUMERICAL INVESTIGATION OF IMMERSION QUENCHING PROCESS FOR CAST ALUMINIUM PARTS USING AN EULERIAN MULTI-FLUID APPROACH

This paper summarizes the improved computational methodology to predict and simulate the heat transfer characteristics presented in immersion quenching processes for cast aluminium parts of internal combustion engines. The numerical model implemented in the commercial Computational Fluid Dynamics (CFD) code AVL FIRE v2013.1 utilized the phase change rate between the heated part and sub-cooled liquid by using an Eulerian multi-fluid modelling approach. Preliminary results of variable Leidenfrost temperature with additional interfacial forces are presented and compare with the measurement results. Different solid part orientations were performed on the step plate test piece with variable thickness along the height, were the temperature and stress analysis were observed. The temperature gradient predicted by the presented model correlate very well with the provided experimental data at different positions.
