This paper is to simulate air pollution at atmospheric conditions forming an inversion layer over a plateau. A wind containing harmful substances blows from a plain to the plateau. A two-dimensional jet, accordingly, was ejected into a two-dimensional channel flow and diffusion of the jet was studied. This is a problem of the aeronautical interference for internal flows as compared with widely reported. external flows which apply to wind and a circular jet. The momentum theory was applied to the channel flow and the jet, treating it as an apparent solid wall. The entrainment effect was also taken into consideration. Theoretical equations were numerically solved. It is found that good agreements exist between the theoretical results and the experimental ones for the loci of the jet made visible by dyes.
