State of the Art of Multi-Dimensional Modeling of Engine Reacting Flows

Ñ State of the Art of Multi-Dimensional Modeling of Engine Reacting Flows Ñ An overview is provided of the state of art and future prospects for the use of CFD simulation in engine analysis and design. The aspects covered include geometry handling and mesh generation, numerical solvers, mathematical modeling of key physical phenomena, exploitation of parallel computers and industrial application. The main conclusions are that: Ð solver and mesh generation methodology developments, allied to parallel computing technology, now enable much more rapid turnaround in CFD simulations than hitherto; Ð physics modeling is at an advanced stage for most aspects of SI combustion simulation, but less so for Diesel combustion and for spray-related processes generally; Ð the overall picture is one of rapidly-increasing use of CFD for engine design; Ð future developments, including the use of LES, promise even better results.
