The use of high-order composite compact schemes for computing supersonic jet interaction with a surface

High-order composite compact schemes are applied to the simulation of viscous gas dynamics with strong discontinuities of flow variables. To perform shock-capturing computations of such problems, the dissipation of the basic operators is enhanced and the solutions obtained with these operators are locally replaced by those produced with the help of simple one-sided differences. Numerical results obtained for the shock interaction of a supersonic axisymmetric jet with a flat surface are presented.
