Abstract

Numerical simulations of high-angle-of-attack flows around slender bodies of revolution are carried out using four different numerical algorithms: a partially flux-split algorithm, the Beam and Warming algorithm in its original and diagonal forms, and an algorithm combining block and diagonal forms. Comparisons of laminar flows at α = 20 and 40 deg reveal that the diagonal algorithm fails to conserve symmetry at high angles of attack and a spurious asymmetry is developed.
