| 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 is developed for the calculation of this flowfield. The computational results demonstrate the existence of the large recirculation regions. The effects of design parameters on the flowfield are discussed. |
