ABSTRACT

The interaction between the gas jet and liquid cross flow is not well characterized for the difficulties in experimental performance. In this paper, a new experimental facility was designed and the evolution of the gas jet in liquid cross flow was captured by the high speed photography. Five experimental cases with different initial liquid cross flow velocities (0.35 m/s, 0.7 m/s, 1.0 m/s, 1.5 m/s, 2.0 m/s) were performed where the momentum ratio of the initial gas jet to liquid cross flow varies to highlight the effects of the liquid cross flow velocity on the flow characteristics. The gas jet morphology and the gas liquid interface were clearly identified from the experimental results, which showed that the gas jet deflected in a less pronounced manner with less unsteadiness generated at the gas liquid interface as the liquid cross flow velocity decreases. Empirical correlations were proposed to predict the characteristic parameters of the submerged gas jet in liquid cross flow.
