RISLarge Curvature Effect on Pulsatile Entrance Flow in a Curved Tube: Model Experiment Simulating Blood Flow in an Aortic Arch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We measured the velocity profiles of pulsatile entrance flow in a strongly curved tube using a laser-Doppler anemometer in order to simulate blood flow in the aortic arch under various conditions, ...
Augmentation of Axial Dispersion by Intermittent Oscillatory Flow
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Gas Dispersion in a Model Pulmonary Bifurcation During Oscillatory Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to clarify the gas transport process in high-frequency oscillation, we measured the axial velocity profile and the axial effective diffusivity in a single asymmetric bifurcating tube, ...
Spatial and Temporal Variation of Secondary Flow During Oscillatory Flow in Model Human Central Airways
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Measurement of Turbulence Intensity in the Center of the Canine Ascending Aorta With a Hot-Film Anemometer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blood flow velocity near the central axis of the canine ascending aorta was measured with a hot-film anemometer. The cardiac output and the heart rate were controlled at will by means ...
