Abstract:   Numerical simulation is an invaluable tool in the development of cleaner combustion technology as it can provide full characterization of the flow field inside an engine. However, obtaining an accurate numerical prediction of the combustion process inside an engine can be difficult. This is because the process is inherently multi-physics in nature and usually occurs in a turbulent flow.

To fully resolve these effects in a realistic engine is computationally prohibitive so they are generally accounted for in simulation using turbulent combustion model. The models that are currently being used in practice span a wide range of fidelity. Nevertheless, most models seek to reduce the complexity of chemistry while capturing the interaction between chemistry and turbulence.

In this talk, I will present several turbulent combustion models and their assumptions. Only rudimentary understanding of flow physics and chemistry is required to grasp the materials presented in this talk.
