Abstract

Large Eddy Simulation (LES) in generalized coordinates was performed using an explicit filtering approach. To simulate supersonic flows, with shocks, filter order was modified in the vicinity of shock from 10th-order in the regions of smooth variation down to 2nd-order at shocks. A 6th-order compact scheme derived from split compact-schemes of Hixon & Turkel1 was used for spatial derivatives. Tests of the approach, especially the Lax & Liu2 problem, have shown the potential of the method to capture shocks and fine scale features accurately. LES of underexpanded jets show close quantitative agreement of mean fields. © 2015, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.
