Abstract
When a low density fluid, such as hot air and helium gas, is discharged from a round nozzle, side jets are generated in the initial region of the jet. These radial ejections of the jet fluid are called side jets. The side-jet formation is estimated by the issuing conditions of the jet flow. The issuing conditions are mainly density ratio between the jet fluid and the ambient fluid, velocity profile and issuing speed at the nozzle outlet. However, a process of side-jet formation has not been revealed even now. In present work, we focused on the flow visualization of a gaseous jet flow with side jets, specifically, the vicinity of a jet nozzle issuing helium gas vertically into ambient air. The helium gas jet with the side-jet is visualized by a planar laser Mie scattering (PLMS) and recorded by a high-speed video camera, in order to investigate the process of side-jet formation.
