An in-house code based on a compact finite difference scheme is introduced and validated. Two distinct turbulent kinetic energy hotspots are identified: one near the wall behind the separation point and another in the free shear layer near the reattachment point. A significant factor contributing to the second amplification phenomenon is elucidated, involving the cluster of shocklets near the reattachment point. Analysis of pressure fluctuation power spectral density reveals concentrated high-pressure fluctuation regions near both separation and reattachment points, with distinct low and mid-to-low frequency phenomena observed, particularly near the separation point.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-170.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Yujoo KANG, Sang LEE<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82241\/ceas-hisst-2024-170<\/p>\n<p>Conference number: HiSST-2024-170<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1409,1407],"tags":[1033,1660,1673,744],"class_list":["post-16984","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-11-hisst-2024","category-11-hisst-2024","tag-computational-fluid-dynamics","tag-direct-numerical-simulation","tag-shock-turbulent-boundary-layer-interaction","tag-supersonic-flow","category-993","category-1409","category-1407","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16984","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16984"}],"version-history":[{"count":4,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16984\/revisions"}],"predecessor-version":[{"id":21268,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16984\/revisions\/21268"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16984"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16984"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16984"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
