TL;DR: In this article, a visualization of highly submerged cavitating water jet has been done using 4-Quik-05 camera, which included obligatory synchronization technique and different types of lens-objectives.
Abstract: In order to study and understand the jet structure and the behavior of cloud cavitation within time and space, visualization of highly submerged cavitating water jet has been done using 4-Quik-05 camera. This included obligatory synchronization technique and different types of lens-objectives. The influencing parameters, such as: injection pressure, downstream pressure and cavitation number were experimentally proven to be very significant. The recordings of sono-luminescence phenomenon proved the bubble collapse everywhere along the jet. In addition, the effect of temperature on sono-luminescence was a point of investigation.
