【 摘 要 】

A numerical technique for computations of turbulent Bows is described. The technique is based on B-splines and allows grid embedding in physically significant Bow regions. Numerical tests, which include solutions of nonlinear advection-diffusion equations and computations of flow over a circular cylinder at Reynolds numbers up to 300, indicate that the method is accurate and efficient. In computations of flow over a cylinder, the lift, drag, and base suction coefficients agree well with existing experimental data and previous numerical simulations. (C) 1999 Academic Press.
