Geometrically Reduced Modelling of Pulsatile Flow in Perivascular Networks
Flow of cerebrospinal fluid in perivascular spaces is a key mechanism underlying brain transport and clearance. In this paper, we present a mathematical and numerical formalism for reduced models of pulsatile viscous fluid flow in networks of generalized

The Dynamics of Pulsatile Blood Flow [PDF]
The theory of dynamic fluid motion involving the forces manifested by mass, acceleration, viscous friction and vessel wall tension have been considered and studied when arterial blood flow and pressure are pulsatile. These studies and considerations have resulted in the conclusion that arterial blood pressure is dependent upon all of these parameters ...

LES of non-Newtonian physiological blood flow in a model of arterial stenosis [PDF]
Large Eddy Simulation (LES) is performed to study the physiological pulsatile transition-to-turbulent non-Newtonian blood flow through a 3D model of arterial stenosis by using five different blood viscosity models: (i) Power-law, (ii) Carreau, (iii ...

Parametric Analysis of Effective Tissue Thermal Conductivity, Thermal Wave Characteristic, and Pulsatile Blood Flow on Temperature Distribution during Thermal Therapy [PDF]
This study examines the coupled effects of pulsatile blood flow in a thermally significant blood vessel, the effective thermal conductivity of tumor tissue, and the thermal relaxation time in solid tissues on the temperature distributions during thermal ...

Cerebrovascular Compliance Within the Rigid Confines of the Skull
Pulsatile blood flow is generally mediated by the compliance of blood vessels whereby they distend locally and momentarily to accommodate the passage of the pressure wave.
