Modeling IC Engine Conjugate Heat Transfer Using the KIVA Code

Abstract

Locating hotspots in metal engine components can be used as an impetus to design a better cooling system. This study focuses on a numerical investigation of a three-dimensional (3-D) transient heat transfer process for a Ford 5.4-L V8 engine. A 3-D transient finite-volume method to solve the heat conduction equation is presented first. This is followed by the implementation of the coupling equations at the gas-solid interface into the KIVA code. The numerical model is validated by a one-dimensional heat conduction problem. Finally, 3-D simulation of the Ford engine with conjugate heat transfer mode is presented and discussed.
