Simulation of High-Speed Flows over an Expansion-Compression Corner Using Large Eddy Simulation

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Large Eddy Simulation over 8 and 25-degree expansion-compression corners at a Mach 3.74 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 Ht&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 station 1 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 flowfield are in agreement with the experimental data.
