Propagation features of an axially symmetric jet in a tube with a permeable wall and closed ends.

Effects accompanying the propagation of the high-pressure axially symmetric gas jet in a tube with permeable walls and closed ends are investigated experimentally. The patterns of smoke visualization of the flows outside the tube, the fields of static pressures along the tube, and the concentration distributions of the jet material along the outer and inner tube walls, depending on the conditions of jet injection are found. The schematic of media flows inside, outside, and through the wall of the permeable tube, in which combining the functions in a form of the jet mixer-ejector in the inner space and burner facility on the outer wall is implied, is suggested.
