Numerical Simulation of Rising Bubble Behavior in Sloshing Condition

The storm and other factors under the ocean conditions could cause the container which exist the free surface on the ship produced the intense sloshing motion.In order to analyze the rising bubble behavior in the liquid under the sloshing conditions.This paper uses the VOF（Volume of Fluid） model to simulate the rising bubbles in the liquid at the fluent platform.Calculation results show that the bubble can cyclical swing up and accompany by aggregation and separation when it is in sloshing conditions.The results also show that the violent sloshing motion can affect the bubble’s departure size,and accelerate the rise of bubbles which along with generating the separation bubbles,it can also hinder the movement of the bubble which can produce the aggregation phenomena,and the bubble will be deviated relatively large displacements in the horizontal direction,it cannot be ignored that the sloshing motion can make a serious impact to the behavioral characteristics of bubbles.
