Multidimensional Cycle Simulation of Flow Field, Combustion and Heat Transfer in a Spark Ignition Engine 920588

Multidimensional cycle simulation is performed for a spark ignition engine for the entire four stroke cycle of intake, compression, expansion and exhaust stroke. Combustion is divided into ignition period and flame propagation period. Simple Arrhenius form is used in ignition and Bray-Moss model is used for turbulence controlled flame propagation. Heat flux is calculated by the wall function method in k-ε turbulence model. Grid is generated by a two dimensional CAD package. Results show proper trends for all flow variables, burning rate and heat flux.
