Abstract: In the computation of compressible fluid flows, numerical boundary conditions are always necessary for all physical variables at computational boundaries while just partial physical variables are prescribed as boundary conditions. In this talk, we associated this issue with the one-sided generalized Riemann problem (GRP) solver so that the extrapolation technique can be actually avoided. Such a one-sided GRP solver shows significant benefits, as numerical experiments demonstrate, on avoiding spurious wave reflections at the computational boundaries. This is a joint work with Prof. J.Q. Li.
