The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...

Abstract Sediments in the seabed hold vital clues to study of marine geology, microbial communities and history ocean life, remote operated vehicle (ROV) mounted tubular sampling is an important way obtain sediments. However, a particularly difficult complicated task due difficulty accessing deep water layers. The affected by sampler’s structural parameters, operation parameters interaction bet...

The traditional procedure of predicting the settling velocity a spherical particle is inconvenient as it involves iterations, complex correlations, and an unpredictable degree uncertainty. limitations can be addressed efficiently with artificial intelligence-based machine-learning algorithms (MLAs). limited number isolated studies conducted to date were constricted specific fluid rheology, part...

We study the flow of concentrated hard-sphere colloidal suspensions along smooth, nonstick walls using cone-plate rheometry and simultaneous confocal microscopy. In the glass regime, the global flow shows a transition from Herschel-Bulkley behavior at large shear rate to a characteristic Bingham slip response at small rates, absent for ergodic colloidal fluids. Imaging reveals both the "solid" ...

Gas-mixing is commonly applied in anaerobic digesters, yet the resulting flow and hydraulic mixing are difficult to evaluate because of limited full-scale experimental data uncertainties integrating sludge rheological data. This study used computational fluid dynamics (CFD) assess impact treated rheology on characterisation a biogas-mixed digester. The CFD model, which was firstly validated usi...

The main objective of this study was to investigate the rheology of mixed primary and secondary sludge and its dependency on solid content and temperature. Results of this study showed that the temperature and solid concentration are critical parameters affecting the mixed sludge rheology. It was found that the yield stress increases with an increase in the sludge solid content and decreases wi...
