Channel width comparison for 2D Two-Phase flows
This test shows the deceleration of a rising bubble due to the distance between lateral walls. As can be seen, the larger is the channel width the faster is the rising bubble. The right hand side figure does not even arrive at the middle of the channel length for the exactly same parameters and time step to all simulat ions presented in this video. The background colors represent the variation of pressure along the channel, where red color indicates high pressure and blue color low pressure.
