Two models for the computation of laminar flames in dust clouds
For researchers in combustion modeling, this provides a validated numerical approach for dust cloud flames, though the work is incremental.
The paper presents two models for simulating premixed combustion in dust clouds, developing a finite volume scheme that respects physical bounds and assessing the consistency of both formulations.
We address two models for the simulation of dust clouds premixed combustion: the first one consists in usual balance equations, to derive the second one, we suppose that the solution takes the form of a travelling combustion wave and track the location of the flame brush by a phase-field-like technique. We build a finite volume fractional step scheme for both models, which respects the natural physical bounds of the unknowns. Then we assess the consistency of both formulations.
