A Combustion Model for Engineering Applications

Currently in the automotive industry, there is a strong demand for robust models to describe homogeneous charge compression ignition (HCCI) or partially premixed compression ignition (PPCI) combustion with high fidelity and computational efficiency. A robust model should describe accurately both the chemistry and the mixing process in the reactive flow. Although computational fluid dynamics (CFD) codes coupled with detailed chemical kinetics can provide accurate insight of the ongoing processes, their high computational cost prohibits their use as a primary engineering tool. In this work a new model is introduced for HCCI and PPCI combustion regimes that can be used in engineering. In particular, the proposed model decouples the resolutions of chemistry and fluid mechanical calculations and allows the introduction of realistic chemical modeling in the calculation of complex engine flows.
