A THEORETICAL AND EXPERIMENTAL INVESTIGATION OF TURBULENT JET INTERACTION.
Abstract
The interaction of two impinging plane turbulent jets was investigated for the purpose of understanding the performance of proportional fluid amplifiers and momentum-exchange devices. Velocity and turbulence profiles were measured across and at various distances along the combined jet axis through the use of a constant temperature hot-wire anemometer. Experimentally determined jet deflection angles were found to agree with those predicted in a previous work by the free-streamline theory. The results, which are presented in terms of normalized parameters, show that the jet interaction may be divided into three regions: mixing; transition; and fully developed. A vena-contracta effect was found to exist in the mixing region. A discussion of each of the three regions is presented in detail along with generalizations for similar geometries. (Author)
