Abstract
Heat transfer is one major important aspect of energy transformation in spark ignition (SI) engines. Locating hot spots in a solid wall can be used as an impetus to design a better cooling system. Fast transient heat flux between the combustion chamber and the solid wall must be investigated to understand the effects of the non-steady thermal environment. This study investigates numerical simulation of 3D transient heat diffusion phenomena in solid, exposed to steady and unsteady thermal boundary conditions. A 3D transient finite volume method to calculate heat transfer across a solid medium will be presented first. It is then validated with steady state thermal boundary conditions. The validation extends to the effects of multiple solid materials for which large thermal property difference is investigated. Finally the effects of non-steady thermal boundary environment are discussed. Numerical results are validated with available analytical solutions and are compared with FLUENT result.
