This paper presents a modified fifth-order WENO-HLLC Riemann solver for the transonic compressible viscous flows around the helicopter rotor in hover. The HLLC approximate Riemann solver is proposed to discrete the convection term involving grid velocity of the Navier-Stokes equations. In order to solve the interface flow accurately. a modified fifth-order WENO scheme is presented by ... https://lightspeedlovers.shop/product-category/spanking-paddles-and-floggers/
