Combustion and Chemical Processing in Turbulent Flows

Turbulent flow, combustion and chemical processing commonly rely on use of models to account of unresolved flow features. This fact is a significant source of error and uncertainty in many engineering flow models. Large scale computing reduces but does not eliminate this problem. We have devised a stochastic convergence approach to such problems which eliminates the need for chemistry models in turbulent combustion. Large eddy simulations with convergence of not only mean quantities, but of the full fluctuation field (probability distribution functions) allow finite rate chemistry without use of chemistry models. Only the simpler and better understood turbulence models are required. Application to turbulent combustion in the engine of a scram jet and chemical reactions in a two phase fluid mixer (contactor) illustrate these ideas.
