Abstract

The flow investigated here appears as a result of the ejecting action of a turbulent jet in conditions when a jet, after emerging from a cylindrical nozzle, impinges into a gas flow channel. Such conditions occur in gas distribution systems. A review of the investigations of flows induced by jets and the solution of a number of problems are contained in [1]. A distinctive feature of the problem investigated below is the stronger development of local characteristics and the specific flow geometry, and also its spatial inhomogeneity. The method of integral transforms is used and formulas for determining the velocity about the nozzle and the flow in the vicinity of jet entry into the gas channel are obtained.
