Dynamical model of bubble path instability
WebMar 1, 2016 · After a previous investigation of the rising motion of a gas bubble in a liquid metal under the influence of a vertical magnetic field, this new study focuses on the case of a uniform horizontal magnetic field. The numerical code is still the same: it is based on a volume-of-fluid technique and on an unstructured Cartesian adaptive grid system. WebOct 1, 2010 · It was shown that the model successfully predicts the hydrodynamic features of the fluidized bed as observed in the experiments. Influence of pressure on bubble rise characteristics such as bubble rise path, bubble stability, average bubbles diameter and bubble velocity through the bed was investigated.

WebMillimeter-sized air bubbles rising through still water are known to exhibit zigzag and spiral oscillatory trajectories. We present a system of four ordinary differential equations which effectively model these dynamics. The model is based on Kirchhoff’s equations and several physical arguments derived from our experimental observations. In the framework of this … WebNov 1, 2024 · In the initial stage of bubble generation, the eccentricity is large and the Weber number (We) of the bubble is small due to the surface tension. In addition, a standard annular flow field and two symmetric vorticities are found around the bubble in the initial stage, by calculating the velocity vector field and vorticity field of water.
