要約

The results of experimental investigations of the behavior of the supersonic high-temperature jet laden with solid particles and its action on an obstacle are presented. A gas generator with a liquid fuel combustor was used as the source of gas emission at a temperature of 1600 K. The parameters of the gas−dust jet are presented. The measurement data for a heat flux from the dusty gas to the obstacle are given. It is shown that the heat flux from the gas, which was laden with solid particles, may be three times greater than that from pure gas. The presented data concerning the cold dust-laden gas jet action on an obstacle address the possible contribution of particle kinetic energy into the heat flux to an obstacle.
