the resolved momentum equation where %$u=\widetilde{ u} + u''$% and %$\widetilde{u''}=0$% with the tilde representing the resolved velocity and the %$''$% double prime the subgrid velocity

%$ { \partial \widetilde{u_i} \over \partial t} + \widetilde {u_j} { \partial \widetilde {u_i} \over \partial x_j} = -{1 \over \rho} {d \widetilde{p} \over d x_i} + {\partial \over \partial x_j} \left( \nu { \partial \widetilde{u_i} \over \partial x_j} - \widetilde{ {u_i}''{u_j}'' } \right)$% where %$ \widetilde{ {u_i}''{u_j}' '} =\widetilde{ {u_i}{u_j}} -\widetilde{u_i} \widetilde{u_j} $%
