Detached-eddy simulation (DES) of a sonic jet flow issuing perpendicularly into a supersonic crossflow is presented. The supersonic boundary layer flow has conditions of incoming Mach number 1.6 and Reynolds number Reδ 1.08×105, based on the free-stream quantities and the boundary layer thickness upstream of the jet exit in absence of jet flow. Both the geometry configuration and flow conditions follow a previous experimental study. The block-structured computational grids are generated with finer meshes in regions where the flow properties have rapidly changes. Some preliminary results are obtained and analyzed. It is found that for this configuration, key flow characteristics observed in experiment are successfully reproduced in the present numerical study, namely jet induced shocks blockage, boundary layer flow separation ahead the jet exit and Kelvin-Helmholtz instability development along the jet shear layer. Simulations are still ongoing with results, findings and comparisons with available experimental data to be included in final full paper.
