High-frequency ventilation is a type of mechanical ventilation therapy applied on patients with damaged or delicate lungs. However, the transport of oxygen down, and carbon dioxide up, the airway is governed by subtle transport processes wh...
On the Origins of Vortex Shedding in Two-dimensional Incompressible Flows [0.03%]
