| Popis: |
An Implicit Large Eddy Simulation of a supersonic underexpanded jet is performed with a high-order Hybrid Weighted Essentially Non-Oscillatory/Central Difference (WENOZ/Central) based solver. A resolution study is performed. Carbuncle instabilities that appear in the region of the Mach disk and barrel shock are mitigated by increasing the numerical dissipation in the region of the shock by adjusting the denominator in the WENO-Z weights. The near nozzle shock structure is in good agreement with published studies and results generated with a lower order finite volume code. An analysis of the energy spectrum and Reynolds stresses in the far field show that the jet is nearly fully turbulent. |
