    In this paper, we present the results of the numerical computations carried out to simulate the direct immersion quenching process of several test pieces such as (1) trapezoidal block, (2) hollow block, and (3) engine-cylinder head using a recently developed and implemented quenching simulation methodology within the commercial computational fluid dynamics code AVL FIRE® v2009. Numerical coupling between the simulation domains, involving the fluid and the solid metal region, are achieved through an AVL code coupling interface (ACCI) feature. While mass, momentum, and energy equations utilizing a multi-fluid framework are employed in the fluid domain, only an energy equation is exercised to establish the variation in the thermal field in the solid region. With this coupled approach, both the phasic effects such as bubble dynamics inclusive of clustering and their disposition, vapor pocket generation in the fluid domain, and the temperature field modification in the solid zone are captured very effectively in a concurrent manner. The results presented in this study include comprehensive descriptions of the flow field information and the temperature pattern in the solid at different time instants. A scrutiny of the registered temperature readings at different monitoring locations with the numerical results generates an overall very good agreement for all the cases presented. The computed information adjudges the presence of intense non-uniformity in the temperature distribution within the solid region which is of grave importance in evaluating the stress and fatigue patterns generated in the quenched object. In summary, the capability of the quenching model in simulating a real-time quenching application process and the efficiency in reducing the overall model size by the application of the ACCI procedure are well demonstrated.
