| Popis: |
The problem of laminar-turbulent transition (LTT) in hypersonic boundary-layer flows is one of the main still unsolved problems of high-speed aerodynamics. LTT leads to a substantial increase of the surface heating and aerodynamic drag of hypersonic vehicles and, thereby as well as affects the efficiency of propulsion system and control surfaces. In this paper we discuss our DNS of a transitional flow over a flat plate at the freestream Mach number 3 and high unit Reynolds numbers. Hybrid difference schemes allow increasing accuracy of numerical data in comparison with fully monotone difference schemes on the same numerical grid. |
