Large Eddy Simulations of Oxy-Coal and Gasification Flames

Gasification simulation


Simulations were performed using ARCHES with a 3.5 million cells domain (filter = 2 mm) for ~100,000 CPU hours for each case on a staggered finite volume mesh. The following images show the influence of particle size on the particle temperature: large particles take a longer time to heat up.

The following video shows the evolution of the coal off-gas, i.e. the fuel coming from the coal particles through devolatilization and oxidation reactions into the gas phase.
