Abstract: A new numerical method has been developed to facilitate the use of unified constitutive equations in finite-element codes. The method has high stability, permits large time increments, and ...

Abstract: The efficiency of axial gas dispersion during ventilation with high-frequency oscillation (HFO) is improved by manipulating the oscillatory flow waveform such that intermittent oscillatory flow ...

Abstract: Axial and secondary velocity profiles were measured in a model human central airway to clarify the oscillatory flow structure during high-frequency oscillation. We used a rigid model of human ...
