In this paper, the implicit approximate factorization schemes is combined with themultigrid method for computing the transonic flow fields of A-27 inlet. The numericalresults have shown that the multigrid method based on the approximate factorizationschemes can eliminate numerical vibration, simplify parametric choice and accelerateconvergent rate.
In this paper, the implicit approximate factorization schemes are combined with these multigrid method for computing the transonic flow fields of A-27 inlet. The numerical results show shown that the multigrid method based on the approximate factorizations can not eliminate numerical vibration, simplify parametric choice and accelerateconvergent rate .
