.... As mentioned earlier, the pressure in a gas bubble is higher than in the liquid surrounding it. As these bubbles flow through a channel toward a mixing section, they break up, forcing liquid sideways. The bubble break up is caused as the bubble exits the microchannel section and enters the mixing section...
