These  phenomena involve complex interactions of boundary  layers with compression or expansion waves and  exhibit a low-frequency unsteady behaviour which  still requires a clear explanation. This study aims  at better identifying the physical mechanisms which  drive the global structure of these flows and  suggesting improved numerical tools in order to  predict these more accurately. The appearance of free  and restricted separations in supersonic separated  jets is more particularly investigated. Various  hypotheses are tested to explain the evolution of the  associated unsteady asymmetric wall pressure field in  function of the nozzle pressure ratio. New numerical  strategies are proposed and lead to identify more  accurately the appearance of free and restricted  separations and the time-varying morphology of the  flow during the transition process. Possible origins  of side-load activities are extensively investigated  by performing the azimuthal expansion of wall  pressure field.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844318562\"\u003e\u003ch3\u003eAPPLICATION TO THE SUPERSONIC OVER-EXPANDED NOZZLE FLOW\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844318562","offer_id":39495972880477,"sku":"9783844318562","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/42f9d1f7-6ab5-4c8e-a378-6b4f106cca6b.jpg?v=1759208067","url":"https:\/\/shop.autorenwelt.de\/en\/products\/numerical-simulation-of-turbulent-shock-induced-separated-flows-von-afaque-shams","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
