Abstract
When solving problems in the field of filtration combustion of gases, numerical methods are often used to analyze
the wave structure depending on changes in the hydrogen content in the mixture and other physical and chemical
parameters. This work analyzes the stationary structure of the wave of filtration combustion of incompressible gas
in the low-speed mode when the parameters of the gas flow and the porous medium change, as well as when the
hydrogen content in the mixture changes. The problem is solved by the numerical Runge-Kutta method of the fourth
order of accuracy, tested on a system of differential equations. Reduced to a dimensionless form, the system of
equations is written in vector format. Programming is performed in Delphi 7. The results presented show agreement
with the known experimental data and also allow us to obtain new conclusions about the structure of the filtration
combustion wave of gases.
