Abstract:

The work presents numerical investigations of flame propagation in a free straight vortex. The simulations rely on the LES technique and presumed-PDF combustion modeling with a chemical mechanism reduced by an ILDM approach which has been validated on a number of test cases. Numerical and experimental study confirm that the phenomenon of the Combustion Induced Vortex Breakdown (CIVB) can take place in an unconfined turbulent vortex with a strong inner axial flow. The LES analysis allowed to determine the main physical mechanisms of this phenomenon.
