Abstract

In present study, the impact of a single bubble on an inclined wall and its movement is investigated by applying volume of fluid method (VOF) in OpenFOAM open source cfd package using a solver called INTERFOAM. Both phases are incompressible and surface tension between the two phases is estimated by CSF method. The effect of some parameters such as CONTACT ANGLE, wall slope and Bond and Morton dimensionless numbers on bubble shapes and velocity are studied. The numerical results show bubble velocity along wall increases with the increase of wall slope angle. Three bubble regimes are recognized and introduced in this study named: sliding, bouncing, and zigzagging based on wall slope. The bubble regime changes from sliding to bouncing when wall slope changes from 30 to 40 degrees. In constant Morton number, increment of Bond number increases both velocity and amplitude of fluctuations. In addition, an increment of Morton number in constant Bond number decreases velocity and amplitude of fluctuations. Moreover, by increment of Morton number, the bubble motion will change from an accelerating motion to a constant velocity condition.
