Abstract
A new type of precombustion chamber has been developed in which coflowing jets with large velocity differences are used. A finite difference calculation procedure based on the SIMPLE algorithm is developed for the numerical simulation of this flowfield. This paper presents a statement of the algorithm, boundary condition specifications, and the results of computational experiments. The computational results demonstrate the existence of the large recirculation regions. It displays significant three-dimensional characteristics. The effects of design parameters on the recirculation features are discussed briefly in the present study.
