Here we present a method for producing noncoalescing monodisperse microbubbles in an efficient, massive and controlled way. Since our prototype is easily scalable, it can be straightforwardly adapted to satisfy the specific gas injection demands required by the different applications where it can be used, like bioreactors or water treatment or purification plants. The main feature of the bubbling device described here consists of injecting the gas at the leading edge of a wing in relative motion with respect to a liquid. The reasons for this particular design relies on the smallness of the drag coefficient of streamlined bodies and also on the fact that the strongest favorable pressure gradients and the minimum values of the liquid pressures are located at the leading edge of the airfoils composing the wing.

借助强压力梯度批量生产单分散微泡的方法

在这里，我们提出了一种以有效，大规模和可控制的方式生产非结块单分散微泡的方法。由于我们的原型易于扩展，因此可以直接进行调整以满足可使用该原型的不同应用（例如生物反应器或水处理或净化厂）所要求的特定气体注入需求。此处描述的起泡装置的主要特征包括以相对于液体相对运动的方式在机翼的前缘处注入气体。进行这种特殊设计的原因取决于流线型主体的阻力系数较小，并且取决于这样一个事实，即最强的有利压力梯度和液体压力的最小值位于组成机翼的机翼的前缘。
