摘要

This paper presents a robust multi-block flow solver for the thin-layer Reynolds-211u001eaveraged Navier-Stokes equations, that is currently being used for industrial 211u001eapplications. A modification of a matrix dissipation scheme has been developed, 211u001ethat improved the numerial accuracy of Navier-Stokes boundary-layer computations, 211u001ewhile maintaining the robustness of the scalar artificial dissipation scheme with 211u001eregard to shock capturing. An improved method is presented to define the 211u001eturbulence length scales in the Bladwin-Lomax and Johnson-King turbulence models. 211u001eThe flow solver allows for multi-block grid which are of C(sup 0)-continuous at 211u001eblock interfaces or even only partly continuous, thus simplifying the grid 211u001egeneration task. Results are presented which show the applicability of the flow-211u001esimulation system for industrial purposes.
