An adaptive Lagrangian method for computing 1D reacting and non-reacting flows (Q1209860)

A method for computing one-dimensional unsteady compressible flows, with and without chemical reactions is presented. This work has focused on the accurate computation of the discontinuous waves that arise in such flows. The main feature of the method is the use of an adaptive Lagrangian grid. This allows the computation of discontinuous waves and their interactions with the accuracy of front-tracking algorithms. This is done without the use of additional grid points representing shocks, in contrast to conventional front-tracking schemes.
