Abstract
It is known that the CI engine combustion process is complex phenomenon. The rapid progress has been made in multidimensional modeling of in-cylinder processes by suitable combination of assumptions and equations that can analyze the critical features. The CFD models gives us the complete understanding of the in-cylinder processes, reduce the cost of the expensive and time consuming experimental techniques. FLUENT is one of the versatile tools which is used for modeling of in-cylinder flows as well as exhaust pollutants. FLUENT has a set of assumptions and restriction. One such restriction is that the effect of Scalar Dissipation Rate Fluctuations (SDRF) is ignored. In the present paper an attempt has been made for the inclusion of SDRF by writing the User Defined Function and appending the same to the existing code FLUENT. Three swirl ratios 2, 3 and 4 with spherical bowl have been chosen and runs are made for these swirl ratios with and without SDRF. The simulated results are compared with the experimental results for validation.
