Abstract:
The gasification of a two-layer solid porous fuel in a combined low-temperature charge of a gas generator has been studied using the developed mathematical model and computational algorithm implemented in the OpenFOAM software. The influence of the two-layer nature of the solid porous fuel on its gasification has been studied in computational experiments using as an example gasifiers containing a fuel based on polymethylmethacrylate and polyethylene with different mutual arrangement of their layers. It has been shown that in a two-layer fuel, two waves of gasification propagate simultaneously, due to which the relative mass flow rate of gasification products can have two local maxima. The operating time of a gas generator using a two-layer porous fuel ambiguously depends on the mutual arrangement of the layers and can go beyond the range between the times of operation of the gasifier using each of the fuels.
