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.
