Pulsating Flow and Platelet Aggregation [PDF]

open access: yes, 2005
Platelet aggregation has been modelled as a nonlinear system of viscous flow and pulsating flow based on the Fogelson’s continuum model. By solving nonlinear governing equations and the coupling between flow and platelet aggregates in the cylindrical coordinates using the finite element method, we can see how the platelet aggregation forms under the ...

Numerical investigation for convective heat transfer and friction factor under pulsating flow conditions

open access: yesMATEC Web of Conferences, 2018
For pulsating flow, the behaviours of the convective heat transfer and friction factor for a periodic corrugated channel are investigated numerically. The finite volume method is used in the numerical study.

Pressure, Flow Rate and Operating Speed Characteristics of a Continuous Flow Left Ventricular Assist Device During Varying Speed Support

open access: yesIEEE Access, 2020
Hydraulic performance of Continuous Flow Left Ventricular Assist Devices depends on their pressure head and flow rate relations. Hydraulic characteristics of these devices are expressed by pressure head and flow rate loops in a pulsatile environment as ...

Application of pulsating jet concept for efficiency improvement of solar-based air heaters

open access: yesCleaner Engineering and Technology
This study employs transient numerical analysis to investigate the hydraulic and thermal performance of a jet solar air heater (JSAH) operating under turbulent pulsating flow conditions, juxtaposed with a conventional solar air heater (SAH). The absorber

Computational Modelling of Pulsating Biological Flow [PDF]

open access: yes, 2004
Computational modelling of biological flow can have many in medicine and biomechanical engineering. Stenosis of blood vessels is the main cause of vascular disease. A mathematical model of pulsating flow through stenotic blood vessels has been formulated.

New Facility for Membrane Fouling Investigations under Customizable Hydrodynamics: Validation and Preliminary Experiments with Pulsating Cross-Flow

open access: yesMembranes, 2022
Flux reduction induced by fouling is arguably the most adverse phenomenon in membrane-based separation systems. In this respect, many laboratory-scale filtration studies have shown that an appropriate use of hydrodynamic perturbations can improve both ...
