This paper discusses a recently improved computational fluid dynamics (CFD) methodology for virtual experimental investigation of the heat treatment for cast aluminium parts. The immersion quenching process of the heated work piece in a sub-cooled liquid pool is handled by employing the Eulerian multi-fluid modeling approach, which is implemented within the commercial CFD code AVL FIRE (R). The applied heat and mass transfer rate is modeled based on a different boiling regime, which is controlled by the Leiden frost temperature. %26lt;br%26gt;The objective of the presented research is to present an updated quenching model by applying variable Leiden frost temperatures. Furthermore, simulation results are compared with available measurements for a wide variety of quenching scenarios involving immersion cooling of the step plate and real cylinder head with different solid parts%26apos; orientations. The temperature histories predicted by the presented model fit very well with the available experimental data at different monitoring locations.
