Abstract
Different TVD principles for non-linear systems of conservation laws will be analysed analytically and numerically. The most appropriate principle for specific problem under consideration will be applied with the new original TVD limiter. Thereafter, accuracy, stability and robustness of coupled and uncoupled approaches when solving chemically reactive fluid dynamics equations will be analysed. After analytic derivation and analysis, numerical schemes will be tested and validated with one-dimensional test cases whereas thereafter they will be extended to solve multi-dimensional problems. Boundary conditions of complex boundary elements capable of dealing with flows with variable gas properties and composition will be derived. Again, they will be first analysed and validated with one-dimensional test problems, whereas, after their successful application to one-dimensional problems, the theory will be extended to solve multi dimensional problems. In the second part of the work novel quasi-dimensional combustion model with pollutant emission formation models will be developed. The accuracy and applicability of the models will be validated with experimental results and with calibrated three-dimensional chemically reactive fluid dynamics software. Multiple original analytical derivations and empirical models will be applied when developing the combustion and pollutant emission formation models. All adequate basic and applied scientific contributions developed during the course of research projects will be incorporated into the original fluid mechanics and thermodynamic virtual engine simulation code with the aim of modelling the pollutant emission formation during transient and stationary operation of an engine. However, basic scientific contributions related to fluid dynamics will be applicable for arbitrary fluid dynamics problems.
