摘要：

The work is devoted to further development of Dispersion-Relation-Preserving (DRP) scheme by C. Tam and coworkers as well as schemes by C. Bogey and C. Bailly aimed at their implementation to nonlinear viscous flows, so far as viscosity plays an important role in sound generation. We will carry out accuracy and stability testing of the numerical algorithms and present some advances in discrete boundary conditions. We concentrate at essentially viscous flows including the 2D Lamb-Oseen and the 3D Taylor Green vortex decay as well as channel flows.
