Summary:

Heat transfer plays an important role in the conceptual and detail design of cooling system of modern DI engine and has considerable influence over their operational performance and durability. The consequential demand for higher possible heat transfer rates has lead to the very promising concept of providing for a controlled transition from pure single-phase convection to subcooled boiling flow in some high thermal load regions. In order to achieve controlled boiling over a wide range of operation conditions, the detailed flow and heat transfer analysis is essential. CFD simulation incorporating the boiling model is an effective approach for such analysis. Four different boiling heat transfer models are proposed and developed within CFD framework, two based on Division Description Method (DDM), and another two based on Superposition Method (SM). The calculation results and the test validation show that Boiling Model A based on DDM and Modified BDL (Boiling Departure Lift-off) Model based on SM are in better satisfactory agreement with the experimental data than other two models under the same conditions and could be used for calculating the boiling heat transfer in cooling water jacket of DI engine. And CFD code adopted is SC/Tetra V7® developed by Software CRADLE Company LTD
