Abstract: The results are given of numerical investigation of the gasdynamic structure of heat-conducting subsonic flows past volumes of low-temperature plasma localized in space. Cases of intense heat release in atmospheric air are investigated, with the gas being heated to $10\,000$–$20\,000$ K so that the local density differences reach tens and hundreds of times. Various modes of gas motion are revealed and investigated, such as steady-state laminar flow past the low-temperature plasma region with partial percolation and unsteady-state oscillating flow modes without and with formation of regions of return motion.
