Abstract
The present paper discusses a mathematical model of 3D compressible, laminar flame flow, considering the Lorentz force action on the development of fuel combustion in a cylindrical pipe. The combustion process is modelled with Arrhenius kinetics using two exothermic chemical reactions. A system of non-stationary partial differential equations with seven unknown functions is analyzed. For the inviscid 2D axisymmetric swirling flow approximation, the implicit finite difference scheme in time with upwind differences in space and the alternating direction method are used. The results of numerical simulation are confirmed by the results of the experimental study of electromagnetic field effect on the thermo-chemical conversion of a biomass mixture (straw+wood).
