How to define the effective coefficient in Q1
 
In turbulence modelling£º

the effective conduction coefficient in energy equation =K/CP1+RHO1*ENUT/Prt K is the conduction coefficient. Prt is the turbulent Prandtl number and was assumed to be unity.

the effective diffusion coefficient in concentration equation =RHO1*DL*FL+RHO1*ENUT*FL/Sct DL£ºdiffusion coefficient of solute in liquid phase(constant) FL£ºliquid mass fraction of solute (variable) Sct:turbulent Schmidt number which was assumed to be unity.
