Reynolds Number Effects on Shock-Wave Turbulent Boundary-Layer Interactions

Large Eddy Simulation of Three Dimensional High Speed Aerodynamic Flows

“…It represents, for example, the deflection of a control surface on a wing. The shock can cause a boundary layer separation upstream of the point of impingement of the primary shock, with a secondary shock forming near the separation (Andreopoulos and Muck 1987, Dolling and Or 1983, Horstman et al 1977, Settles et al 1979, Smits and Muck 1987, Zheltovodov et al 1983, Zheltovodov and Yakolev 1986, and Zheltovodov 1996. Reynolds-averaged Navier-Stokes simulations have failed to accurately predict the flow characteristics (Knight and Degrez 1998) such as fluctuating pressure and heat transfer.…”

Shock-Turbulence Interaction: Annotated Reference

“…The influence of Mach number and Reynolds number for a limited range of both parameters have been experimentally investigated by Mateer and Viegas (197%, in the earlier work by Horstman et al (1977) and by Green (1970). The highest Mach number range in wedge generated shock turbulent boundary layer interactions were Russian experiments covering the Mach number range from about 3 to 4 reported in Gol'dfel'd (lgS5) who used both hot wire anemometry and LDV for the turbulence data.…”

Correlations to predict turbulent streamwise influence regions and onset of transition in supersonic flows

“…The start of the upstream influence was defined as the x location at which the skin friction of the disturbed solution For the case of a compression ramp (see Fig. 6.2), a comparison has been made with the upstream influence length obtained in various experiments [6]- [12]. The flow parameters in these experiments are within the valid range of the developed correlation function.…”

“…[3], who developed the scaling of the upstream pressure influence parameter based on a surface pressure criterion. A comparison of the upstream influence length prediction using the experimental upstream pressure influence criterion results [12], and the skin friction criterion used in the current study is shown in Figure 6.5. The results are plotted for Res0 ~ 1.3 X 10 6 .…”

“…[1]- [12]. Settles et al [2,3] have performed the most notable work in correlating the upstream influence region in the presence of a compression ramp, based on the "upstream pressure influence" criterion.…”
