Abstract
As a fundamental study of the mixture formation process of the impinging diffusion direct injection diesel engine, characteristics of the unsteady gas jet impinging onto a projection on a wall was numerically studied.Numerical analysis was carried out on a 2-dimensional incompressible unsteady flow with two different gases of different density. The program code used was based on the SOLA scheme, which was expanded so that the density change caused by the mixing of the two different density of gases can be treated.Numerical results are able to describes the nature of the mixture formation process of the unsteady gas jet impinging onto a projection on a wall, which had been obtained through the authors' previous experimentation.
