Distribution of mass, velocity, and intensity of turbulence in a two-phase turbulent jet

Research output: Contribution to journal › Article › peer-review

Abstract

The effect of small liquid droplets on the flow structure of an axially symmetrical turbulent air jet was studied. The flux of the droplets was measured and correlated by a normal-distribution curve with a spreading coefficient of 0.05. Distributions of lime-average and fluctuating longitudinal velocities were measured and correlated. In general the two-phase jet is narrower than the single-phase one, with smaller normalized velocity fluctuations. Studies of the spectra and probability density functions indicated that the discontinuous phase causes suppression of turbulence in the dissipation range, namely at high wave numbers. This effect is proportional to the droplets’ concentration in the investigated range.
