Description

Spectral methods for the small disturbance equation of transonic flows are developed. Two schemes are presented. One of the is spectral in chi and y of second order in tau. The other is spectral in chi and of second order in y and tau. A method for extracting a highly accurate solution for problems containing a discontinuity is presented. The solution is obtained by fitting the standard spectral approximation to a sum of a step function and a truncated Chebyshev series. An application to the Burgers equation and to the small disturbance equation is described
