Estimate of Constants in the K−ε Model of Turbulence by Using Large Eddy Simulation

抄録

Constants in the k−ε model are estimated using the statistics obtained from a large eddy simulation of a turbulent mixing layer. Estimated values are compared with those usually adopted in the k−ε model and those derived by statistical analysis. It is shown that the estimate using large eddy simulation can give an important clue to the optimization of the constants and improvement of the model.
