Highly accurate compact flowfield dependent variation method for solving two-dimensional navier-stokes equations

A higher order accurate method, namely high order compact flowfield dependent variation (HOC-FDV) method, has been developed to solve full Navier-Stokes equations. The scheme is a third order accuracy in time and fourth order accuracy in space. The spatial derivatives in the third order accuracy in...
