Interaction of a weak shock with freestream disturbances

The development of a new transonic small-disturbance model to analyze the interactions of freestream disturbances with a weak shock is discussed. The model demonstrates that diffraction effects, nonlinear steepening effects, focusing effects and induced vorticity fluctuations interact simultaneously...

Zusammenfassung:	The development of a new transonic small-disturbance model to analyze the interactions of freestream disturbances with a weak shock is discussed. The model demonstrates that diffraction effects, nonlinear steepening effects, focusing effects and induced vorticity fluctuations interact simultaneously to determine the development of the shock wave in space and time and the pressure field behind it.
