Pulsatile cerebral paraarterial flow by peristalsis, pressure and directional resistance

Fluids and Barriers of the CNS, 2023
Background A glymphatic system has been proposed that comprises flow that enters along cerebral paraarterial channels between the artery wall and the surrounding glial layer, continues through the parenchyma, and then exits along similar paravenous ...

Numerical investigation on vortex-induced vibration response characteristics for flexible risers under sheared-oscillatory flows

International Journal of Naval Architecture and Ocean Engineering, 2019
Surge motion of top-end platform induced by periodic wave makes marine flexible riser encounter equivalent sheared-oscillatory flow, under which the Vortex-induced Vibration (VIV) response will be more complicated than pure sheared flow or oscillatory ...

Hydrodynamic Forces of a Semi-Submerged Cylinder in an Oscillatory Flow

Applied Sciences, 2020
This work experimentally investigated the performance of hydrodynamic forces on a semi-submerged cylinder under an oscillatory flow. To generate the equivalent oscillatory flow, the semi-submerged cylinder is forced to oscillate in several combinations ...

Oscillatory Carreau flows in straight channels [PDF]

Royal Society Open Science, 2020
The present paper studies the oscillatory flow of Carreau fluid in a channel at different Womersley and Carreau numbers. At high and low Womersley numbers, asymptotic expansions in small parameters, connected with the Womersley number, are developed. For the intermediate Womersley numbers, theoretical bounds for the velocity solution and its gradient ...

In-Vitro Experimental Modeling of Oscillatory Respiratory Flow in a CT-Scanned OSAHS Tract

Applied Sciences, 2020
Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a highly prevalent respiratory disorder. The knowledge of respiratory flow is an essential prerequisite for the establishment and development of OSAHS physiology, pathology, and clinical medicine.
