A review of the available literature indicated that cognition of the behavior of jets normal to a moving stream was lacking.The object of this investigation was therefore
To study the problem reduced to its simplest form; that of a two-dimensional jet normal to a moving stream.
To determine the feasibility of the proposed measuring techniques.
It was not intended that the results of this work necessarily have an immediate direct application.Rather it was to lay the foundation for future work along the same lines but with more complex situations should the techniques prove satisfactory.
With reference to the study of a two-dimensional jet normal to a moving stream, and for the limited number of variables involved, it may be stated
The penetration of a two-dimensional jet normal to a moving stream is a function of the jet density and velocity, the moving stream density and velocity, the distance downstream of the jet and the diameter of an equivalent area circle.
The diffusion of a two-dimensional jet normal to a moving stream depends on the distance from the wall containing the jet orifice, the distance downstream of the jet, the jet velocity and the moving stream velocity.
With reference to the feasibility of the proposed measuring techniques, it may be stated
The use of carbon dioxide for the jet, the withdrawal of samples with a single small probe and the analysis of the samples with an orsat apparatus is feasible. The different densities of the gases produce very good schlieren and shadow photographs.
