This paper deals with a simplified model taking into account the interplay of compressible, laminar, axisymmetric flow and the electrodynamical effects due to Lorentz force’s action on the combustion process in a cylindrical pipe. The combustion process with Arrhenius kinetics is modelled by a single step exothermic chemical reaction of fuel and oxidant. We analyze non-stationary PDEs with 6 unknown functions: the 3 components of velocity, density, concentration of fuel and temperature. For pressure the ideal gas law is used. For the inviscid flow approximation ADI method is used. Some numerical results are presented.

... In reference [10], a study was conducted to model the combustion process with Arrhenius kinetics. The model considers a single-step exothermal chemical reaction between fuel and oxidant in a cylindrical pipe, taking into account the electrodynamical effects due to the Lorentz force action on the combustion process. ...

... In [16], [20] (Kalis et al.), the combustion process with Arrhenius kinetics is modelled using simple exothermic chemical reactions and taking into account the electrodynamic effects due to the action of the Lorentz force on the combustion process in a cylindrical pipe. A 2D axially symmetric nonstationary physical model for the inviscid (Reynolds number Re = ∞), compressible swirling flow of ideal gas with two components of velocity u r , u z , with circu-lation v = ru φ , density ρ, concentration of chemical species, temperature and electromagnetic force is analyzed. ...

... This aligns with the cur rent study's findings, where magnetic treatment of blast re agents enhanced the overall efficiency of gasification by in creasing carbon participation rates. [18] further explored the impact of gradient magnetic fields on swirling flame dynamics during biomass gasification, observing enhanced burnout of volatiles and cleaner heat energy production. These studies collectively suggest that magnetic fields can be effectively ap plied to various gasification processes to improve efficiency, control combustion characteristics, and potentially reduce emissions. ...
