Simulating the Combustion in a DI Diesel Engine Applying a New Model for the Conditional Scalar Dissipation Rate

The Representative Interactive Flamelet (RIF)-model offers a method of separating the numerical effort associated with solving the governing equations for the turbulent flow field from that of the chemistry. This is possible since the chemical time scales can be considered very small compared to those related to the turbulence. The concept has gained widespread recognition owing to its ability of capturing the essential physics underlying combustion. The objective of this paper is to show how a more accurate description of mainly the soot formation and oxidation processes in a high-speed small-bore Direct Injection (DI) diesel engine can be realized within the framework of the RIF-model. This is achieved by deriving a new model for the conditional scalar dissipation rate, describing the transport in the flamelet.
