摘要：
Partially-averaged Navier-Stokes (PANS) method, as a bridging method between Reynolds-averaged Navier-Stokes (RANS) and direct numerical simulation (DNS), has attracted many researchers' attentions in recent years. In this paper, PANS is extended to the simulations of a jet injected into a supersonic crossflow. A dynamic function of the resolution control parameter f(k) (unresolved-to-total ratio of kinetic energy) is adopted. Numerical results are compared to the experimental data and the performance of PANS is evaluated. The predictions of dynamic f(k) PANS overall agree well with the measurements and the instantaneous flow filed is provided. In addition, the distribution of fk is presented to have a better understanding of the method's scale resolving behavior throughout the computation domain. Current study has shown the capabilities and potential of PANS method for supersonic industrial flows.
