In this talk, we present the velocity error analysis of -conforming DG method for the semi-discrete time-dependent Navier-Stokes equations at high Reynolds number.  By introducing the Raviart-Thomas interpolation operator, we prove that when the condition is satisfied, the error of the velocity, which is pressure-robust and Reynolds-robust, is quasi-optimal. Numerical experiments are carried out to verify the analytical results.
