Hi,
The subgrid stress tensor T_ij = (1/3)*d_ij*T_kk - 2*nu_sgs*Sbar_ij I am pretty sure that T_ij is referred to as B in OF. Now (1/3*d_ij*T_kk) = (2/3)*k*I And Sbar_ji is 0.5*(dU_i/dx_j + dU_j/dx_i) That can be found by symm(grad(U)). could anybody explain to me why do we use dev(symm(grad(U)) ? Best Regards, Vishwa |
