Application of segregated approach on reacting flow field simulation in combustion chamber

Popis výsledku v původním jazyce

a segregated approach of reacting flow field simulation is described in this paper. The segregation is based on different flow and thermodynamic properties in each region. The flow field is highly unsteady with the chemical reaction between species in the region of the flame tube. There is possible to apply a simplified model of flow in a bypass channel where the flow does not contain chemical reactions. Therefore, a simple thermodynamic model is used and an assumption of steady state flow is applied. This approach was applied to a number of cases where significantly reduce computational resources. In this paper are discussed potential improvements of the segregated approach which allows solving heat transfer through the flame tube wall or application of mixed RANS - LES turbulence models.
