Abstract:
Dual-stream nozzle jet computations conducted using different numerical algorithms developed in TsAGI and KIAM RAS are presented. Scale-resolving approaches of DES family based on higher accuracy numerical methods are applied. The flow considered was studied experimentally at ITAM SB RAS. The jet was axisymmetric up to the influence of the supporting pylons, cold, subsonic at the inner nozzle exit and supersonic at the outer nozzle exit. The computational data is compared with the experiment and with each other.
