NASA Technical Reports Server (NTRS) 19720006656: An Analytical Investigation of an Oscillating Wedge in a Supersonic Perfect Gas Flow. Ph.D Thesis - North Carolina State Univ., Raleigh
Several aspects of the oscillating wedge are investigated to evaluate both the resulting trends for the wedge and methods of analyzing unsteady flows. An existing hypersonic small disturbance theory for an oscillating thin wedge is extended and applied. A perturbation method involving linearization about the known flow is then derived and discussed. Subsequently, a finite difference technique for calculating the complete unsteady flow field of the wedge in motion is presented and discussed in conjunction with some calculated quasi-static nonlinear trends.
