The Effect of Pulsatile and Non-Pulsatile Extra Corporeal Perfusion on Cerebral Oxygen Saturation in Cardiopulmonary Bypass Patients (Flow Type On Cerebral Oxygenatıon) [PDF]
Aim:The flow type generated by a heart-lung machine is important in cardiopulmonary bypass. The use of pulsatile flow versus non-pulsatile flow during cardiopulmonary bypass has been a controversy among clinicians. We compared the effect of non-pulsatile

Pulsatile flow in model cerebral aneurysms [PDF]
AbstractWe present an immersed boundary method based on volume penalization, with which pulsatile flow in a model cerebral aneurysm is simulated. The model aneurysm consists of a curved vessel merged with a spherical cavity. The dominant vortical structures arising in the time-dependent flow are discussed and the evolution of the maximal shear stress ...

Characteristics of flow patterns under pulsatile flow with same oscillatory fraction in the grooved channel [PDF]
The characteristics of flow structure under pulsatile flow with same oscillatory fraction in the grooved channel are investigated experimentally. The flow patterns under pulsatile flow in the grooved channel are divided into 4kinds in this study.

Pulsatile Flow Measurement by a Speckle Triangle Assessment
The blood flow in the coronary artery (CA) is pulsatile and much higher than that measured in the brain, retina, and skin before. Its quantitative measurement is medically significant in the coronary artery bypass grafting (CABG).

LES of additive and non-additive pulsatile flows in a model arterial stenosis [PDF]
Transition of additive and non-additive pulsatile flows through a simple 3D model of arterial stenosis is investigated by using a large eddy simulation (LES) technique. We find in both the pulsatile cases that the interaction of the two shear layers, one

Convective instability and transient growth in steady and pulsatile stenotic flows [PDF]
We show that suitable initial disturbances to steady or long-period pulsatile flows in a straight tube with an axisymmetric 75%-occlusion stenosis can produce very large transient energy growths.

The method to generate pulsatile circulatory fluid flow using microfluidics
Microfluidic chips provide versatile tools to mimic the biological effect of blood flow on pluripotent stem cells (PSC). This paper presents methods for the use of microfluidics to model embryonic circulation using differentiated PSC.
