Supersonic cascade flow

Application of an Analytical Method to Locate a Mixing Plane in a Supersonic Compressor

“…In some cases, the entry flow may therefore be supersonic over the entire-or upper-span. The resulting physics of the flow field in the entry zone can be complex because Compressor 92 of the interaction between compression and expansion waves [1][2][3]. Besides, shock waves propagating upstream the blades are dissipative and must necessarily be taken into account in the prediction of the stage performances [4].…”

Supersonic Wave/Blade-Row Interactions Establish Boundary Conditions for Unsteady Inlet Flows

“…For axial Mach numbers above this limit, the re ection coef cient is uniformly one for any value of¯u , as given by Eq. (2).…”

“…If the in ow parameters are given in the stationary frame, then the solution process for a moving blade row consists of transforming all mean ow quantities to the blade-xed coordinate system and subsequently calculating the wave coef cients using Eqs. (2)(3)(4).…”

Unsteady transonic flows in an axial flow compressor

“…We first construct the solution between two parallel lines along which £ is constant as are also the quantities u, v and p. The periodic solution may therefore be generated by replacing (x, y) by (x + \, y + m) and so on. Evidently the profile must be a concave/convex one, compare Lichtfuss and Starken (1974) pp. 56-61.…”

“…Kantrowitz, having developed a working supersonic compressor, explained its operation in terms of a two-dimensional model which is now standard, c.f. Levine (1957), Stratford and Sansome (1959), Hutton (1974) and Lichtfuss and Starken (1974), from an extensive literature.…”
