The effect of bubble induced turbulent structures on the mass transfer of non-spherical bubbles
Abstract
Although mass transfer from bubbles to liquid is essential for the prediction of the efficiency of reactors, the mass transfer from bubbles is not fully understood. To determine the effect of the local velocity profile on the mass transfer for a wobbling bubble with an Eötvös number of 2 and a Morton number of 10-11, 15 simulations were performed with a Front Tracking method using a sub-grid scale model for the mass transfer in the vicinity of the interface. The vortical structures created by the bubble are influenced by the exact physical properties chosen for the liquid and gas. These changes in the vortical structures also resulted in changes in mass transfer. In addition, the vortical structures created transport barriers between the wake and the bulk of liquid, which were identified by the high-value Finite Time Lyapunov Exponents. These barriers prevent convective mass transfer from the bubble wake to the bulk of the liquid. Therefore, mass transfer from the gas phase to the bulk liquid should take into account both the mass transfer from the gas to the liquid and the transfer from the wake to the bulk of the liquid.
