Modeling and Simulation of Film and Transitional Boiling Processes on a Metallic Cylinder During Quenching


A multiphase flow and heat transfer model is used to simulate the flow field and the heat transfer process of a metal specimen located in a flow during the quenching process. The applied bubble crowd model is able to investigate the separate boiling phases within one single numerical model approach. Simulation results are discussed for the quenching of a circular cylinder in a facing water flow. The initial flow velocity and the wall superheat (at temperatures above and below the Leidenfrost point) are varied to investigate their influence on the vapor formation and on the local as well as the averaged heat transfer rates. Characteristic differences between the heat transfer on the different surfaces of the cylinder due to their orientation in the flow field are discussed.
