Masking aerosols in non-lethal means of destruction of violators

The results of physical and mathematical modeling of an aerosol curtain in a guarded room during the combustion of pyrotechnic composition are presented. The large-scale effect of increasing the lifetime of an aerosol curtain with an increase in the volume of the room and a constant range of visibility in smoke is demonstrated. The effect is due to an outstripping increase in the amount of heat injected into the room with smoke (in proportion to the volume of the room) compared to the amount of heat released into the walls, floor and ceiling of the room when the smoke cools (in proportion to their area). The influence of the shape of aerosols on the characteristics of an aerosol curtain is shown. The demonstrated large-scale effect should be taken into account both when evaluating the test results of aerosol generators and when planning the use of aerosol generators in protected areas.
