Web1 Jun 2024 · A high order accurate shock-capturing scheme for gas-dynamic equations is developed. • Its performance is largely comparable to the 5th order accurate WENO-Rusanov scheme. • Very high resistance against shock anomalies such as carbuncle phenomenon is achieved. • Its computational cost is 30–40% less than that of the above WENO scheme. • WebFirstly, a shock detector based on nonlinear weights is used to identify grid cells with high gradients or discontinuities throughout the whole flow field. Then, WCNS (weighted compact nonlinear scheme) is adopted to capture shocks in these areas, while the smooth area is calculated by CPR.
