摘要

摘要通过直接数值模拟，考虑了马赫数 M = 2.5 时超音速完美气流流线型平板上马赫波与边界层的相互作用问题。研究了入射马赫波强度对层流-湍流转换（LTT）的影响。研究表明，振幅为 5%（模拟风洞侧壁粗糙度的相对厚度）的马赫波在边界层上的入射会导致在平板上的边界层中形成湍流楔。

Numerical Simulation of the Interaction of a Mach Wave and a Boundary Layer on a Flat Plate

Abstract

Using direct numerical simulation, a problem of the interaction of a Mach wave with a boundary layer on a flat plate, streamlined by a supersonic perfect gas flow at the Mach number M = 2.5 is considered. The influence of the intensity of the incident Mach wave on the laminar-turbulent transition (LTT) is studied. It is shown that the incidence of a Mach wave with an amplitude of 5%, simulating the relative thickness of the roughness on the side wall of the wind tunnel, on the boundary layer leads to the formation of a turbulent wedge in the boundary layer on a flat plate.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
