FEM/FVM Modelling of Processes in Combustion Engine

Popis výsledku v původním jazyce

In the paper, the authors present their approach to numerical modelling of processes in a combustion engine and its present situation. The modelling was motivated by the aim to compute production of nitrogen oxides during the work cycle of such an engineThere are the models of flow of compressible gas, heat and mass transport, and chemical reactions and their connection presented here. The model of flow is built on the finite element approximation of Navier-Stokes and compressible continuity equations.Transport problem is solved using finite volume method applied to the advection equation and the energy equation. Chemical reactions are modelled as local mass and energy sources in each finite volume. "All three models use the same mesh in each time step; the mesh changes in time. The model is partially tested and produces globally relevant data, but the aim of modelling of production of nitrogen oxides is not achieved, yet."
