Numerical Experiments with CONCHAS-SPRAY: Compression Stroke of an External-Chamber Diesel Engine

摘要

The CONCHAS-SPRAY computer program has been used to simulate the compression stroke of an external-chamber Diesel engine. We predict that the strongest fluid motions in the external chamber occur at the time fuel is injected, the peak temperature is 7% below an idealized adiabatic prediction, and the peak pressure is 10% lower. We also show an example of a simple procedure for generating grids for complex engine geometries. (ERA citation 09:003117)
