The L-stable second order single diagonal implicit Runge-Kutta method for finding a solution of nonlinear Navier-Stokes equations in rotation form in the L-shaped domain is applied. An Rν-generalized solution of the problem in weighted sets is defined. An unweighted finite element method is constructed to find its approximate solution. The results of numerical experiments have shown the advantage of the proposed method over the classical ones.
