Abstract

Presents the results of modelling combustion products of solid propellant flow. The product of combustion is the ionized gas occurring in a channel with current conducting walls, when a part of the channel is in the external homogeneous magnetic field, oriented in such a way that the ponderomotive force, occuring in the flow region, is opposite to the flow. This results in gas deceleration and increase of static pressure. For the condenensed systems, whose mass burning rate is in direct proportion to the environment pressure, the static pressure increase causes increase of mass burning rate. The basic parameters have been determined by numerical simulation. The nature of their influence on the process of combustion in a cylindrical channel has also been determined. The study revealed that a ten-fold increase of burning rate is possible at moderate values of the parameter of magnetogasdynamic interaction.
