The circulatory transport system is responsible for oxygen and nutrient supply to all body tissues and removal of waste products. The discovery of the circulation of blood in the human body is related to William Harvey (1578–1657). The circulatory system consists of the heart—the pump that generates the pressure gradients needed to drive blood to all body tissues, the blood vessels—the delivery routes, and the blood—the transport medium for the delivered materials. The blood travels… Expand
Simulation of blood flow in the abdominal aorta considering penetration into the organs using pore network model
One of the critical limitations of studies on cardiovascular blood flow simulation is to determine outlet boundary conditions accurately. In the present study, for the first time, pore network modelExpand
Simulation of Blood Flow through Stenosed Artery
Results show that the percentage of stenosis affects the wall shear stress (WSS) the most and the effect of various blood models like Newtonian, Power law, Carreau, and Cross models on the fluid dynamic factors. Expand
Cardiovascular function in ectotherm sauropsids
The results support the idea that pulmonary bypass may improve digestive function by supporting gastric acid secretion and buffering the postprandial alkaline tide rather than being an adaptation to extended diving periods in crocodiles. Expand
A Review of Computational Hemodynamics in Middle Cerebral Aneurysms and Rheological Models for Blood Flow
Cerebrovascular accidents are the third most common cause of death in developed countries. Over recent years, Computational Fluid Dynamics simulations using medical image-based anatomical vascularExpand
Human erythrocyte filterability at low driving pressure.
It is proposed that the anomalous increase in RBC deformability was caused by RBCs undergoing spontaneous mechanical fluctuations, where RBC filterability is monotonically and asymptotically increasing. Expand
Effects of Aggregation on Blood Sedimentation and Conductivity
A method for calculating blood conductivity based on effective medium theory is presented and it is experimentally demonstrated that the disaggregated cells settle much slower than the aggregated cells, which could be examined as a potential means of accelerating ESR tests in clinical practice.

Effects of perfusion and vascular architecture on contrast dispersion: Validation in ex-vivo porcine liver under machine perfusion
Dynamic contrast enhanced ultrasound (DCE-US) enables imaging of cancer angiogenesis by quantification of perfusion and dispersion. Although increased perfusion may be found in areas of activeExpand
The influence of inlet velocity profile and secondary flow on pulsatile flow in a model artery with stenosis
The results of an experimental investigation to determine the influence of two physiologically relevant inlet conditions on the flow physics downstream of an idealized stenosis are presented. The twoExpand
A Novel Electromagnetic Actuation System for Magnetic Nanoparticle Guidance in Blood Vessels
Targeted drug delivery using magnetic nanoparticles (MNPs) is a new therapeutic method and is being improved continually. However, recent improvements have focused mainly on the introduction andExpand
A Novel Scheme for Nanoparticle Steering in Blood Vessels Using a Functionalized Magnetic Field
To reduce the sticking ratio of nanoparticles, a novel field function scheme is proposed that uses a simple time-varying function to separate the particles from the walls and guide them to the target point and confirmed the effectiveness of the proposed magnetic field function method for steering nanoparticles for targeted drug delivery.

Flow through such tubes is a special case of Bernoulli's theorem for the flow of viscous liquids, and under certain circumstances it is described with a reasonable degree of accuracy by a modification of the Hagen-Poiseuille law for tubes of elliptical cross section. Expand

It was found that the geometry and flow rate ratio at bifurcations greatly influence the flow separation zones and it is also important to consider elasticity, pulsatility and non-Newtonian flow behavior in large blood vessels in zones where secondary flow is developed and flow separates zones are formed.

The relation of pulsatile pressure to flow in arteries
General agreement between observed and calculated flow curves has been found and so establishes the validity of the theoretical derivation based on general hydrodynamic principles and also justifies the method of recording flows. Expand
Flow visualization studies in a mold of the normal human aorta and renal arteries.
To study the flow behavior in regions where hemodynamic effects have been suggested to participate in atherogenesis, we evaluated flow in a mold of the aorta and renal arteries of a previouslyExpand
Flow and pressure drop in systems of repeatedly branching tubes
The airways of the lung form a rapidly diverging system of branched tubes, and any discussion of their mechanics requires an understanding of the effects of the bifurcations on the flow downstream ofExpand

While oscillatory measurements will be useful in assessing rheological parameters that may give insight into the fundamental aspects of flow of normal and pathological bloods, it is not clear that the elastic component of the complex viscosity of blood will be of significance in physiological pulsatile flow.

Computer simulation of the mechanically-assisted failing canine circulation
Pressure and flow waveforms throughout the circulation as well as ventricular pressure and volume were calculated for the normal, failing, and assisted failing circulation to assess the effects of cardiac assistance. Expand
Computer simulation of local blood flow and vessel mechanics in a compliant carotid artery bifurcation model.
A numerical model for the blood flow in the human carotid artery bifurcation has been developed and the comparison of the results for a rigid and a distensible wall model demonstrates quantitative influence of the vessel wall motion. Expand
An experimental study of pulsatile pipe flow in the transition range.
The study of pulsatile flows is relevant to many areas of applications. Typical applications include aerodynamics, biofluid mechanics, wind flows, and gas transport. Transition to turbulence duringExpand
