In this paper, authors consider the propagation of a shock wave of extremely low intensity
from a pure gas to a heterogeneous mixture consisting of solid particles suspended in a gas
and having an electric charge. The mathematical model used takes into account the speed and
thermal interaction of the carrier and dispersed components of the mixture. The force interaction
of particles and gas included the Stokes force, the strength of the attached masses, as well as
the dynamic force of Archimedes. The carrier medium was described as a viscous compressible heat-conducting gas. The equations of the mathematical model were solved by the explicit finitedifference
method of the second order of accuracy, using the non-linear correction of the grid
function. The system of equations of the mathematical model was supplemented by boundary
and initial conditions for the desired functions. As a result of numerical simulation, it was
found that in an electrically charged gas suspension there is a difference in pressure and gas
velocity, the velocity of the dispersed component, from similar values in a gas suspension with an
electrically neutral dispersed component. The revealed differences in the parameters of the carrier
medium during the propagation of a shock wave from a pure gas into a neutral and electrically
charged dusty medium arise due to the force interaction of the gas and solid components of a
heterogeneous mixture, the solid component of which is affected by the Coulomb force.
