Further Development of Eddy Dissipation Model for Turbulent Non-Premixed Combustion Simulation

In view of the application limits modified eddy dissipation model (MEDM) in simulations weakly turbulent flow, compressible and internal an improved (IEDM) is proposed. The IEDM uses dissociation reactions to obtain correct combustion temperature instead specific heat compensation used MEDM model. This extends flow simulation. simulation accuracy for by using accurate transport property maximum ε/k limited give a reasonable reaction rate near walls, expression parameter A also updated. Nine flames including seven jet two opposed are simulated with Compared experimental data flames, peak differences 189 161 K, respectively, indicating minor improvement 131 7 significant
