Unsteady shock front waviness in shock-buffet of transonic aircraft

Weak Shock Reflection Modeled by the Unsteady Transonic Small Disturbance Equation

A Shock Tube Driven Transonic Wind Tunnel

A small transonic wind tunnel was designed, constructed and calibrated in order to provide a tool for the study and demonstration of transonic flow phenomena. The wind tunnel makes use of flow properties following the propagation of a shock wave along a tube in order to create the transonic flow. This is in contrast to conventional transonic facilities which are supplied from a reservoir or com...

DNS of unsteady shock boundary layer interaction

A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...

Upstream propagating curved shock in a steady transonic flow∗

We derive a new set of equations to give successive positions of slowly moving and slowly turning curved shock front in a transonic flow. The equations are in conservation form two of these are kinematical conservation laws. keywords Curved shock propagation, shock dynamics, ray theory, transonic flow.

A I AA-85-0369 Shock Waves in Transonic Channel

thereby producing a nearly monotonic transition of flow properties through the shock Structure. Evidently, under these conditions, the dissipative terms in the modified governing equations are large in magnitude compared to the dispersive terms. The behavior of shock waves in transonic channel flow with varying Reynolds and Prandtl numbers is examined using analytical and numerical methods. It ...
