Interaction of a vortex ring with a diffusion flame
(AIP Publishing, 2002-02)
The interaction between a laminar vortex ring and a flat diffusionflame is investigated via direct numerical simulations. The diffusionflame is generated by a “spark” and is implemented as initial condition for the ...
Flame–vortex interaction in a reacting vortex ring
(AIP Publishing, 1998-01)
Direct numerical simulations are used to study the flame–vortex interaction in a laminar reacting vortex ring. The chemical reaction occurs by a one-step, Arrhenius-type reaction that mimics the combustion of typical ...
Local flow topology and velocity gradient invariants in compressible turbulent mixing layer
(Cambridge University Press, 2015-06-04)
The local flow topology is studied using the invariants of the velocity gradient tensor in compressible turbulent mixing layer via direct numerical simulation (DNS) data. The topological and dissipating behaviours of the ...
A priori assessment of the subgrid scale viscous/scalar dissipation closures in compressible turbulence
(Taylor & Francis, 2013-11-18)
An appraisal is made of several subgrid scale (SGS) viscous/scalar dissipation closures via a priori analysis of direct numerical simulation data in a temporally evolving compressible mixing layer. The effects of the filter ...
