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.

Effects of anesthesia on cerebral blood flow, metabolism, and neuroprotection
Journal of Cerebral Blood Flow and Metabolism, 2018 Administration of anesthetic agents fundamentally shifts the responsibility for maintenance of homeostasis from the patient and their intrinsic physiological regulatory mechanisms to the anesthesiologist.

Non-invasive optical measurement of arterial blood flow speed [PDF]
arXiv, 2021 Non-invasive measurement of the arterial blood speed gives rise to important healthinformation such as cardio output and blood supplies to vital organs. The magnitude andchange in arterial blood speed are key indicators of the health conditions and development andprogression of diseases.

Effect of blood's velocity on blood resistivity [PDF]
, 1998 Blood resistivity is an important quantity whose value influences the results of various methods used in the study of heart and circulation. In this paper, the relationship between blood resistivity and velocity of blood flow was evaluated and analyzed ...

Capillary K+-sensing initiates retrograde hyperpolarization to locally increase cerebral blood flow
Nature Neuroscience, 2017 Blood flow into the brain is dynamically regulated to satisfy the changing metabolic requirements of neurons, but how this is accomplished has remained unclear. Here we demonstrate a central role for capillary endothelial cells in sensing neural activity

Exploring noise-induced chaos and complexity in a red blood cell system [PDF]
, 2021 We investigate dynamical changes and its corresponding phase space complexity in a stochastic red blood cell system. The system is obtained by incorporating power noise with the associated sinusoidal flow. Both chaotic and non-chaotic dynamics of sinusoidal flow in red blood cell are identified by 0-1 test.

A cellular automaton model for tumour growth in inhomogeneous environment [PDF]
, 2003 Most of the existing mathematical models for tumour growth and tumour-induced angiogenesis neglect blood flow. This is an important factor on which both nutrient and metabolite supply depend. In this paper we aim to address this shortcoming by developing

Palabos-npFEM: Software for the Simulation of Cellular Blood Flow (Digital Blood) [PDF]
Journal of Open Research Software (2021), 2020 Palabos-npFEM is a computational framework for the simulation of blood flow with fully resolved constituents. The software resolves the trajectories and deformed state of blood cells, such as red blood cells and platelets, and the complex interaction between them. The tool combines the lattice Boltzmann solver Palabos for the simulation of blood plasma

Regulation of Coronary Blood Flow.
Comprehensive Physiology, 2017 The heart is uniquely responsible for providing its own blood supply through the coronary circulation. Regulation of coronary blood flow is quite complex and, after over 100 years of dedicated research, is understood to be dictated through multiple ...
