This study presents Stereoscopic particle image velocimetry measurements of a precessing motion resulting from sudden expansion an axisymmetric jet into coaxial chamber. The has ratio 4.9 and aspect 2.03. velocity profile in the inlet tube is measured upstream using Laser doppler anemometry. Reynolds number (Re) varied 3160 to 63,870. time-averaged flow field exhibits behavior, near resembles t...

It is well known that certain pathological conditions result in a decrease of red blood cells (RBCs) deformability and subsequently can significantly alter the blood flow in microcirculation, which may block capillaries and cause ischemia in the tissues. Microfluidic systems able to obtain reliable quantitative measurements of RBC deformability hold the key to understand and diagnose RBC relate...

BACKGROUND The effect of temporal and spatial gradients in shear on primary human endothelial cell (HUVEC) proliferation was investigated. The sudden-expansion flow chamber (SEFC) model was used to differentiate the effect of temporal gradients in shear from that of spatial gradients. With a sudden onset of flow, cells are exposed to both temporal and spatial gradients of shear. The temporal gr...

The paper investigates the liquid polymer-bitumen binder in a pipe with sudden expansion. At small values of expansion parameter, formation high-viscosity zone occurs axial region, and effective viscosity decreases at periphery nearwall zones. destruction process structural bonds, which intensively proceeds near flow from supply pipe, leads to decrease viscosity. corner area reverse flows is ac...
