英文摘要	Large-scale structures in two- and three-dimensional, spatially developing, compressible mixing layers are visualized. The convective Mach number Mc is prescribed to be 0.4 and 0.8. Direct numerical simulations were performed using a Discontinuous Galerkin method. Special attention is paid on the panorama of spatial evolution of large-scale structures, as well as on the compressibility effect on these structures. Fine structures such as the sonic waves at the inlet, and shocklet structures for the Mc = 0.8 case are also visualized. For the three-dimensional cases, in order to show the spatial evolution of the large-scale structures more clearly, both the and Q (2) structure extraction methods colored with stream-wise velocity magnitude are utilized. The "H-type" secondary instability structure and the "forest" structures are evident. It is found that the method gives better results in the case of high compressibility effect shear flows.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000321872600009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Interdisciplinary Applications; Imaging Science & Photographic Technology; SCI(E); 1; ARTICLE; 3; 219-227; 16
