Abstract
Large Eddy Simulations over 8 and 25-degree expansion-compression corners at Mach3.74 and 2.9 are performed. The dynamic turbulent inflow boundary condition is calculated by another Large Eddy Simulation over a flat plate with a newly introduced recycling rescaling method named H$_t$&p in which total enthalpy, static pressure, and three components of velocity are scaled back from the recycling station to the inflow condition. The generated turbulent flow at the averaging station is close to the experimental data at station1 before the flow reaches the expansion corner and the predicted displacement and momentum thicknesses are accurately predicted. The calculated averaged surface pressure at the centerline of the expansion-compression corner and the static pressure profiles at several locations in the flow field are in agreement with the experimental data. In the final paper, the results of the simulations of the expansion-compression corner at Mach 2.9 will be presented. © 2024 by Nadia Kianvashrad.
