The hydrogen jet injection through a circular orifice into a transverse supersonic M = 3.38 flow is investigated numerically in the current paper. The 3D computations are performed under the conditions of the experiments by Ben-Yakar (2006). The Delayed Detached Eddy Simulation (DDES) approach is used to describe the transient flow’s features. The results of the numerical simulations are compared to the experimental data. A good qualitative agreement between the calculations and the experiment is obtained for the mean flow structure, bow shock position, and jet penetration depth. The use of the scale-resolving DDES approach made it possible to obtain in the calculations large vortex structures developing at the boundary between the jet and the main flow, making a considerable contribution to mixing primary and secondary gases.
