The mixing and axial transport of smoke in oscillatory tube flows


To gain a better insight on the mechanisms of transport in high-frequency ventilation, we examined the transport of smoke in a straight tube, a model of the trachea. A smoke bolus was injected into a ventilator, and the movement of the smoke along the tube was monitored by a laser-photomultiplier system. With this system we studied the instantaneous… (More)
