The operation and performance of Bubble Column Reactors (BCR) rely heavily on gas injection geometry and its operation since all other hydrodynamic parameters such as gas void fraction, bubble properties, mass transfer, liquid velocity and so on depend on the gas injection. In this study, the bubbly flow rig has been designed and fabricated to find out the optimum design for bubble injection mechanism delivering swirl bubble motion in gas liquid flows. Different configurations of open channels have been designed for momentum dissipation to inhibit the rotary liquid motion and to facilitate the swirl movement for bubbles in the stationary liquid. The swirl motion can have a stronger effect on the hydrodynamics and the performance of bubbly reactors than the conventional bubbly flow. In this study a Particle Image Velocimetry (PIV) technique has been applied on single as well as two phases for a system with water and air as the working fluids, sucessfully.
