A new rotating flux method based on moving grid is introduced to solve the two-dimensional Euler. We employ the adaptive moving grid method, which is based on the variational principle and uses the second-order accuracy of conservative-interpolation for physical quantities at the new grids, for the new grid distribution according to the solution property. Physically, the new rotating entropy stable numerical flux, which is obtained by Rotating Invariance and satisfies the second law of thermodynamics, is utilized as the numerical flux function at the new irregular quadrilaterial cell. The numerical results provides the remarkable evidence in stability and high-resolution.
