The present study investigates the effect of taking into account the time dependency of the fine (subgrid) scales in a residual-based variational multiscale approach for large eddy simulation. The residual-based variational multiscale method with time-dependent (dynamic) subgrid scales is presented,
In this article, large eddy simulation is used to simulate homogeneous shear ows. The spatial discretization is accomplished by the spectral collocation method and a third-order Runge-Kutta method is used to integrate the time-dependent terms. For the estimation of the subgrid-scale stress tensor, t
