This paper presents zonal detached-eddy simulation of a round underexpanded sonic jet exhausting from a realistic aircraft afterbody and controlled by four radial injections. The comparison with a former experiment proves the capability of zonal detached-eddy simulation to reproduce mean flow induced by the complex interaction between the compressible waves and the turbulent jet shear layer. However; the very near-field jet structure indicates that the shear-layer transition to a fully turbulent state is delayed. Therefore; a modification of the characteristic length scale used in the modeling is proposed which is shown to improve the prediction of the shear-layer growth. The control injectors are aimed to enhance jet mixing. Experiment indicated the efficiency of this additional device but also expressed the need for more data to get a deeper and more complete insight into the whole flowfleld. Both spatial and temporal information are provided by zonal detached-eddy simulation which is then a good candidate. This method is shown to correctly simulate streamwise vortices generated by secondary injections; their action in jet distortion; as well as their subsequent decay. Finally; computational results allow us to evaluate the action of the hypermixer on turbulent activity and its consequences on jet dilution;
