Abstract

This paper presents the development of a two-dimensional high-order solver with an unstructured spectral difference (SD) method coupled with the nonlinear lower-upper sym- metric Gauss-Seidel method to solve the algebraic systems arising from SD discretizations with a second-order backward difference formula for time marching. The solver employs the formulations of Sun et al.¹ and Van den Abeele et al.² This method is used to solve the 2D flow around a circular cylinder at Re = 300, 800, 1000 and M = 0.05, the NACA0012 airfoil at Re = 50000 and M = 0.4 at zero angle of attack and the 2D flow around a square cylinder at Re = 10000 and M = 0.05. The obtained results are compared with reference solutions.
