Flame in a buoyant methane layer
WebMoreover, boundary layer profiles at the ceiling layer are also studied. The turbulent velocities obtained from both the inlet-types are really low in near-field, with plume remaining intact without any mixing until it hits the ceiling, resulting in an over-predicted vertical velocity along the centreline. ... • Buoyant methane flame is ...

In the spirit of laminar-flamelet modelling of non-premixed turbulent combustion, a diffusion flamelet is studied. However, the flamelet is also taken to end at a finite position. Such an end of a diffusion flame exhibits fuel-rich and fuel-lean premixed elements as well as the diffusion flame-sheet itself—a structure that is known ... the port 1521 is already in useWebSummary. When a light fluid is injected at a steady rate at the roof of a tunnel in which there is a turbulent main flow of a heavier fluid, the turbulent diffusion of the light layer may be considerably reduced due to buoyancy. For large Richardson numbers turbulent mixing ceases altogether.
