Concept
Eddy Dissipation is a model used to predict the rate of turbulent mixing and reaction in combustion processes, where the rate of reaction is assumed to be controlled by the rate of turbulent mixing of reactants. It simplifies the complex chemistry of combustion by focusing on the turbulent eddies that dominate the mixing and reaction rates, making it particularly useful in engineering applications for predicting flame behavior and pollutant formation.
