HI
I want to use the following relation R_=(2*k_/3)*I + ((k_*(1-Clrr2))/(Clrr1+Glrr/epsilon_-1))*(Plrr/epsilon_ - (2*Glrr/(3*epsilon_))*I) [where Plrr = -twoSymm(Rlrr_ & fvc::grad(U_)) Glrr =0.5*tr(Plrr) and Clrr1,Clrr2 are constants.] in k-epsilon model insted of bossinesque relation: {(2.0/3.0)*I*k_ - nut_*2*symm(fvc::grad(U_))} for reynolds stress tensor. HOW I CAN DO THIS? ANY COMMENT IS APPRECIATED DEEPLY. THANKS IN ADVANCE. MSHA |
