The Effect of Pulsatile and Non-Pulsatile Extra Corporeal Perfusion on Cerebral Oxygen Saturation in Cardiopulmonary Bypass Patients (Flow Type On Cerebral Oxygenatıon) [PDF]
Namık Kemal Tıp Dergisi, 2019 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]
Procedia Computer Science, 2011 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]
, 2020 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.

Large-Eddy simulation of pulsatile blood flow [PDF]
, 2009 Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall.

Pulsatile Flow Measurement by a Speckle Triangle Assessment
Frontiers in Physics, 2021 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]
, 2010 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
