Shock oscillation in highly underexpanded jets Project supported by the National Natural Science Foundation of China (Grant No. 11602028) and the Science and Technology Project of General Administration of Quality Supervision Inspection and Quarantine of China (Grant Nos. 2017QK119 and 2017QK188). |
(color online) Cross spectra and relative phases of pressure fluctuation on either side of the jets obtained under different simulation conditions for NPR = 5.60 by using (a) one equation SGS model with coarse mesh and (b) Smagorinsky model with fine mesh. |
