Abstract:

A computational technique for one-dimensional, unsteady flow is presented. The technique emphasizes the role of discontinuities shocks, contact discontinuities, gradient discontinuities by treating them explicitly. Points inside regions of continuous flow are treated by a finite difference scheme of second order accuracy. Theoretical and practical arguments to support such an approach are given. The technique allows the computational time to be reduced to a minimum. The accuracy of the results as well as the generality of the program are shown by many applications to one-dimensional and quasi-one- dimensional problems.
