作为治病救人的常规行业,制药公司需要输送高质量药品的系统。有一种用泡沫包裹的换能器,能利用声悬浮器产生声波。并利用来自声波的声力,将化学粒子悬浮于换能器之间,并将它们混合到一个无污染空间中。

阿贡国家实验室的 Kamlesh Suthar 和 Chris Benmore 使用 COMSOL Multiphysics 软件模拟了声悬浮器,目的是找到用以控制换能器之间各个液滴形成方式的最佳几何结构。此外,他们还利用了黏度和表面张力的改变会如何影响液滴形状。通过流固耦合(FSI)的研究,Suthar 对声压级、材料属性及悬浮器几何结构进行了探测。模拟声悬浮器帮助他们完善了自己的设计,实现了对液滴间相互作用方式的进一步控制,这些最终都将有助于推动医药品不断进步以更好的治病救人。
