Large Eddy Simulations of Oxy-Coal and Gasification Flames

Oxy-coal flame simulation


The following simulation was performed using ARCHES with a 41 million cells domain (filter = 1.25 mm) for ~110,000 CPU hours on a staggered finite volume mesh.

The following videos show the particle number density and temperature for small and large particles and also the gas temperature.

Video 1: Number density of small particles (40 microns)

Video 2: Number density of large particles (100 microns)

Video 3: Gas Temperature

The first two videos show the influence of particle size on particle dispersion and particle clustering. The third video shows detailed characteristics of the flame and clusters of small particles which initiate flame ignition.
