Features of interaction of an axisymmetric gas jet with a barrier of high-permeability material

Complex diagnostics (shadow shooting, smoke imaging, gas analysis) has shown the formation of flows at inleakage of a carbon-dioxide gas jet onto a porous barrier on its surface, inside it, and behind it, as well as the flow circulating between the nozzle and the barrier. The spatial distribution of CO$_2$ concentrations and the scheme of flows at jet interaction with a barrier are presented.
