One method is to use irreversibility Wl0Qe
One method is to use irreversibility, which is used to reduce shock [ ], such as the ENO method, in which numerical dissipation partially (numerical dissipation) is also used in the Fourier range (from Through an exponential filter). In the physical realm, we have a method through ENO polynomial interpolation.
Among these methods, we can mention the method of Yi et al. [ ] The so-called characteristic filter method (with little difference or limited volume) successfully deals with shock simulation.
We have another method by Gottlieb [ ] using Gegenbauer polynomials to solve partial Fourier summation. Some good numerical results of the filter approach can be found in Refs [, , , ].
Some problems may prevent the successful use of the filter method in shock relief. In our view, there are two fundamental issues that are critical to the success of the spectral filter method
