Reconstruction of bubble trajectories and velocity estimation Krimerman, Michael
Abstract
This thesis addresses the problem of tracking bubble trajectories and velocities in transparent fluids, in particular we deal with water. It belongs to the area known as fluid imaging. Using long exposure images with the aid of computerized tomography, we are able to track the trajectories of micro-bubbles by first reconstructing the fluid volume containing the bubbly flow. From this volumetric data we then extract bubble trajectories by following the streaks left behind by each moving bubble. Consequently, these streaks are used to estimate bubble velocities. All of this is achieved using a limited number of consumer quality video cameras. In addition, we show how similar data that might be obtained from tracer particles could be used to calculate the velocity vector field within the fluid interior.
