| Abstract | ||
| ABSTRACT The present investigation is mainly concerned with experimental studies on the hydrodynamic characteristics of vertical plunging liquid jet, impinging on a liquid surface. To study the structure of biphasic zone below the free surface of liquid, needle type electrical conductivity probe has been designed and extensively used for the present study. To visualize the two-phase flow field, a high-speed digital camera is also used. The present study provides new methods and application of phase detection probe to understand the physics of the plunging jet aeration system. Apart from the air entrainment characteristics, the geometry of the biphasic zone for the vertical plunging liquid jets also has been investigated. The experimental results are also compared with the existing correlations and are found to be in good agreement. The overall study contributes to the better understanding of air entrainment process and bubble dispersion for the vertical plunging liquid jets. | ||
