Oscillatory-Flow PCR Microfluidic Chip Driven by Low Speed Biaxial Centrifugation [PDF]

open access: yesBiosensors, 2023
PCR is indispensable in basic science and biotechnology for in-orbit life science research. However, manpower and resources are limited in space. To address the constraints of in-orbit PCR, we proposed an oscillatory-flow PCR technique based on biaxial ...

Erythrocyte Aging, Protection via Vesiculation: An Analysis Methodology via Oscillatory Flow [PDF]

open access: yesFrontiers in Physiology, 2018
We demonstrate that erythrocyte deformations, specifically of a type as occur in splenic flow (Zhu et al., 2017), and of the type that promote vesiculation can be caused by simple, yet tailored, oscillatory shear flow. We show that such oscillatory shear

Oscillatory Disturbed Flow Enhances Inflammatory and Oxidative Stress Markers in Endothelial Cells [PDF]

open access: yesMethods and Protocols
Hemodynamics significantly impact the biology of endothelial cells (ECs) lining the blood vessels. ECs are exposed to various hemodynamic forces, particularly frictional shear stress from flowing blood.

Numerical Study on the Non-Oscillatory Unstarted Flow in a Scramjet Inlet-Isolator Model

open access: yesAerospace, 2022
For successful scramjet engine operations, it is important to understand the mechanism of the inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, the mechanism of low-amplitude oscillatory unstarted flow is still unclear.

Hovering in oscillatory flows [PDF]

open access: yesJournal of Fluid Mechanics, 2016
We investigate the hovering dynamics of rigid bodies with up-down asymmetry placed in oscillating background flows. Recent experiments on inanimate pyramid-shaped objects in oscillating flows with zero mean component demonstrate that the resulting aerodynamic forces are sufficient to keep the object aloft.

The Half-Range Moment Method in Harmonically Oscillating Rarefied Gas Flows

open access: yesFluids, 2021
The formulation of the half-range moment method (HRMM), well defined in steady rarefied gas flows, is extended to linear oscillatory rarefied gas flows, driven by oscillating boundaries.

The Improving the Thermal Performance of a Heat Exchanger using a New Passive Technology

open access: yesTikrit Journal of Engineering Sciences, 2023
In this study, the oscillation technique was applied in a multi-tube heat exchanger with baffles. The Nusselt number was investigated in the heat exchanger (HE) over a wide range of operating conditions, Reynolds number (Re =205-3200), and oscillatory ...

Effects of oscillatory flow on fertilization in the green sea urchin Strongylocentrotus droebachiensis. [PDF]

open access: yesPLoS ONE, 2013
Broadcast spawning invertebrates that live in shallow, high-energy coastal habitats are subjected to oscillatory water motion that creates unsteady flow fields above the surface of animals.

Optimum Geometric Bifurcation under Pulsating Flow Assuming Minimum Energy Consumption in Cardiovascular System, an Extension on Murray’s Law [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
In a bifurcation including a mother artery and two daughter arteries, the energy drop is minimum, if, the cube of the radius of the mother artery equals the sum of the cube of the radii of daughter arteries.
