Effect of a transverse entrainment flow on the characteristics of a turbulent jet

We have experimentally investigated the influence of a transverse entrainment flow (wind) on the trajectory of a turbulent jet, as well as on the distribution of the concentration of the gas being discharged along that jet (hydrogen, helium, nitrogen). The entraining flow of air is formed in open space. Its trajectory falls out along points corresponding to the maximum concentrations in the lateral cross section of the jet. We have derived empirical relationships between the jet trajectory and the gas-concentration distribution along that trajectory in their dependence on the hydrodynamic parameter.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 2, pp. 188–191, August, 1990.
