摘      要：This study presents a modification of the central-upwind Kurganov scheme for approximating the solution of the 2D Euler *** prototype,extended from a 1D model,reduces substantially less dissipation than *** problem arises from over-restriction of some slope limiters,which keep slopes between interfaces of cells to be *** study reports the defect and presents a re-derived optimal *** experiments highlight the significance of this formula,especially in long-time,large-scale simulations.
