| 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.
