Numerical Investigation of Strong Crossing Shock-Wave/Turbulent Boundary-Layer Interactions

Abstract: Numerical results are reported for very strong fully separated three-dimensional crossing shock-wave/turbulentboundary-layer interactions at Mach 5. The ow eld is generated by two sharp ns mounted at angle of attack on a at plate in a manner closely resembling a portion of a scramjet inlet. Two symmetric con gurations with n angles of attack of 18 and 23 deg are considered. The ow eld is determined through solution of the full three-dimensional mean compressible Navier-Stokes equations using a sophisticated k-… Show more

“…It should be noted that none of the strong, swept, 3-D interactions of the current database exhibit secondary separation (Panaras 1996), likely precluded by the relatively small Mach number. Schmisseur & Gaitonde (2001) discuss the genesis of secondary separation in the context of both swept and crossing shock interactions. The presence of secondary separation would introduce additional complications to this discussion of mean-flow scaling and is worthy of follow-on investigation.…”

“…(7) Generally speaking, the concept of lower and upper bifurcation points may be introduced for both β 2 and each one of parameters (4), (8) where k = 1, 2, 3, 4, and the vector f = f(β 1 , β 2 , H, V) consists of four components which may be arranged in any sequence for unification of notation of (8).…”

“…That success was leveraged to propose flow models for the SF [24], SCR [25], and double-fin (DF) [26] interactions. Additional efforts have refined RANS-based observations over the years [27][28][29][30][31].Initially, it was unclear whether the fully developed 3-D interactions would exhibit conical or cylindrical symmetry [32]. However, the principle of quasi-conical symmetry emerged, supported by evidence that such symmetry was observed for a variety of interactions produced by geometrically dissimilar shock generators [33].…”
