... system, which maintains the low back pressure that pulls in air from the room and creates supersonic flow through the test section. At Mach 3, the test section pressure is 2.7 kPa and the ejector back pressure is 20 kPa . A custom designed diffuser achieves the necessary pressure...

..., and remains well conditioned in the incompressible limit of the equations. To extend the method to transonic and supersonic flows containing shocks, a hybrid formulation is described, which combines a conservative preconditioned Roe method with the nonconservative preconditioned characteristic-based method...

... multiscale method. In this paper, we carry out numerical experiments with inviscid supersonic flows around cylinders and spheres to evaluate the performance of the Y Z β shock-capturing combined with the V-SGS method. The cylinder computations are carried out at Mach numbers 3 and 8, and the sphere...

... on the supersonic flow to highlight the viability of the compressible extension to FSM. The cylindrical code ( 17 ) employs sixth-order accurate compact differences and fourth-order accurate differences in the radial and streamwise directions, respectively. To preserve accuracy, all finite differences...

...M. Amabili; F. Pellicano The aeroelastic stability of simply supported, circular cylindrical shells in supersonic flow is investigated by using both linear aerodynamics (first-order piston theory) and nonlinear aerodynamics (third-order piston theory). Geometric nonlinearities, due to finite...
