Study of path instability of a rising oil droplet using PIV
Abstract eng: This paper presents an experimental study of the dynamics of a rising oil droplet in water. The motion is associated with path, velocity and shape instabilities. In this work, the former two instabilities have been studied. A three-dimensional visualization of the trajectory of the rising droplet has been presented. A stereo-PIV analysis was conducted on the system for visualization of the velocity field generated by the motion of the droplet. Two distinct type of trajectories were observed and the liquid droplet were found to follow two types of paths - straight and zig-zag. Helical paths were not observed in our study. Vorticity plots calculated from the velocity field are used to explain the observed trajectories.
