In the present work, detailed studies of 2D TVC are investigated by using both experimental and numerical methods. For an active cavity flow case, the present results reveal that the pressure drop value across the combustor increases with the mainstream Reynolds number (Rems) due to the higher velocity gradient between the cavity and mainstream flow. Experimental results indicate that the norma...

Propane combustion in a trapped vortex combustor (TVC) is characterized via large eddy simulation coupled with filtered mass density function. A computational algorithm based on high order finite difference (FD) schemes, is employed to solve the Eulerian filtered compressible Navier-Stokes equations. In contrast, a Lagrangian Monte-Carlo solver based on the filtered mass density function is inv...

In this paper we report a new development on the numerical model for aluminum-steam combustion. This model is based on diffusion flame of continuum regime and the thermal equilibrium between the particle and the flow field, which can be used to calculate the aluminum particle combustion model for two phase calculation conditions. The model prediction is in good agreement with the experimental d...

An experimental investigation into the detailed mixing, combustion and ignition processes occurring in a flow field under the influence of resonant acoustic perturbations has been performed. These acoustic perturbations were created by a pulse combustor of the "Helmholtz" type. Cycle-resolved ensemble-averaged measurements of the velocity field, combined with instantaneous images of chemilumine...
