Dynamic mesh adaption for supersonic combustion waves modeled with detailed reaction mechanisms. Incl. 1 CD-ROM (Q2763520)

The thesis presents adaptive dynamical mesh refinement techniques for hyperbolic conservation laws using a heuristic criterion based on weighted gradients in space and time. Applications deal with two-dimensional numerical simulation of supersonic reactive flows governed by reactive compressible Euler equations with complex chemistry. The numerical scheme is based on an upwind finite volume discretisation on unstructured triangular grids. The time discretisation is either of explicit or of linearized implicit type with adaptive time-stepping. Numerical examples include different non-reactive and reactive flow simulations. The enclosed CD-ROM contains several animations of numerical computations and the source code in C of the developed two-dimensional Euler code.
