Large eddy simulation of propane combustion in a planar trapped vortex combustor
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...
متن کاملTwin Cavity 2D Trapped Vortex Combustor
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...

متن کاملLaminar and Turbulent Aero Heating Predictions over Blunt Body in Hypersonic Flow
In the present work, an engineering method is developed to predict laminar and turbulent heating-rate solutions for blunt reentry spacecraft at hypersonic conditions. The calculation of aerodynamic heating around blunt bodies requires alternative solution of inviscid flow field around the hypersonic bodies. In this paper, the procedure is of an inverse nature, that is, a shock wave is assumed a...
متن کاملFlow characteristics over a tractor-trailer model with and without vane-type vortex generator installed
An experimental study has been conducted to investigate the effects of vane-type vortex generators in affecting the flow pattern of the wake region using a 1:20 scale tractor-trailer model. The de Haviland wind tunnel of the University of Glasgow was employed in this study. Surface oil flow visualisation, smoke visualisation and twocomponent time-averaged particle image velocimetry measurements...
