Supercomputing applications in internal combustion engine design and analysis

Supercomputing applications in internal combustion engine design and analysis are introduced in this paper. The grid generation procedure, flow field modeling, fuel spray and combustion models are briefly reviewed. Results for three example cases: motoring flow in a pent-roof engine, charge distribution in a DISC engine, and coherent flamelet combustion model are given to illustrate the current status and future prospects of supercomputing in the automotive industry. It is expected that further development and cost reduction in supercomputing will allow accurate simulation with an increased number of grid points and more realistic physical models.
