Abstract

The characteristic vortex formation in the ventricles is believed to be affected at an early stage of heart diseases. First, post-processing of patient-specific data has to be standardised. The chosen methods, a combination of Eulerian and Lagrangian techniques, are characterised by means of necessary spatial and temporal resolutions. Second, the goal is to find the best cost-benefit approach for modelling of the mitral valve, as it affects vortex formation and progression in the left ventricle.

Abstract

This work contributes to an improved understanding of the driving mechanisms of the upstream propagation of turbulent premixed flames in enclosed vortex tubes within stationary gas turbine combustion systems. For this purpose, a Flamelet approach based on coupling a transport equation of the flame surface density with the description of laminar Flamelets to turbulent conditions is developed. This coupled approach enables the deduction of an explanation of this flashback phenomenon.
