In this paper pulsatile blood flow through rigid circular tubes due to a sinusoidally varying pressure gradient is analyzed using a microcontinuum model of blood. A new boundary condition, which is in accord with experimental observations on blood flow in small rigid tubes, has been proposed to describe red blood cell rotations at a solid boundary ...

Pulsatile Flow in Hemodialyzers
Journal of Dialysis, 1978The present work is concerned with the calculation of NaCl transfer in flowing solutions and its dependence upon flow characteristics at hemodialyzers. A theoretical analysis of the solute transfer in a hemodialyzer is presented. Experiments were carried out with a continuous flow flat-plate dialyzer.

Turbulence during pulsatile flow has been suggested as a possible mechanism to enhance the transport of gases during high-frequency ventilation. Experimental studies on oscillatory flow in straight, circular tubes have identified three types of flow: (a) laminar; (b) conditionally turbulent, in which high-frequency disturbances occur during the ...

On Steady and Pulsatile Flow of Blood
Journal of Applied Mechanics, Transactions ASME, 1974 The steady and pulsatile flow of blood through small rigid, circular tubes has been analysed by a microcontinuum approach. The exact solutions for velocity and cell rotational velocity are obtained.

Impact of Pulsatile Flow on Microcirculation
ASAIO Journal, 2004Baba and associates 1 have investigated the effects of pulsatile and nonpulsatile flow using a total artificial heart on the microcirculation of the bulbar conjunctiva in a goat model. They have clearly documented that erythrocyte velocity and the number of perfused capillaries were significantly higher with pulsatile flow when compared with ...

MR angiography with pulsatile flow
Magnetic Resonance Imaging, 1992To achieve acceptable scan times, current multiple thin slice and 3D MR angiography (MRA) methods usually are based on continuous data acquisition, without ECG-synchronization. The purpose of this work is to study consequences of pulsatile blood flow for the 2D inflow method.

Pulsatile Flow in Microfluidic Systems
Small, 2019AbstractThis review describes the current knowledge and applications of pulsatile flow in microfluidic systems. Elements of fluid dynamics at low Reynolds number are first described in the context of pulsatile flow. Then the practical applications in microfluidic processes are presented: the methods to generate a pulsatile flow, the generation of ...

Heterogeneous medium enhanced angiogr- ams are key diagnostic tools in clinical practice; the associated hemodynamic information is crucial for diagnosing cardiovascular diseases. However, the dynamics of such medium in physiological blood flow are poorly understood.

Hence does arise the action and function of the heart, which by pulsation it performs. [William Harvey, De Motu Cordis, 1628.] THE study of blood flow as a pulsatile phenomenon is scarcely new, but it has gained new impetus from three recent developments: the commercial production of reliable blood flowmeters, the formulation of theories appropriate to

Pulsatile and Nonpulsatile Blood Flow
JAMA: The Journal of the American Medical Association, 1965Decreased pulsatile blood flow may occur in certain clinical conditions in which congenital or acquired constriction is present in a major artery. Coarctation of the aorta, renal arterial stenosis, and arteriosclerotic narrowing of visceral and peripheral arteries may produce significant dampening of the pulse wave distal to the site of partial ...
