My feeling is that the time-scale constant CL ≈ 0.15 is an approximation of CL = Cmu^ (3/4), where Cmu = 0.09 for the standard k-epsilon model [1]. In OpenFOAM the DRW model uses CL = 0.16431 instead. For the RSM model I'm not sure why they use CL ≈ 0.30, but I believe that the rationale … WebSet Injection Propertiesor Set Multiple Injection Propertiesdialog box, as described in Sections 23.3.15and 23.3.18) and the physical models you are using in conjunction with the discrete-phase model.
