Simulation of the BP‐80 Blood Pump

Artificial Organs, 2001
Abstract: In this study, computational fluid dynamics (CFD) analysis was applied to investigate the flow within a commercially available Biopump, BP‐80 (Medtronic, Minneapolis, MN, U.S.A.). The Biopump was selected because, for this purpose, a great number of experimental hemolysis data is available.

Blood Flow SPH Simulation with Elastic Deformation of Blood Vessels

2019 IEEE 19th International Conference on Bioinformatics and Bioengineering (BIBE), 2019
Blood vessels are responsible for the distribution of nutrients and oxygen to all cells in the human body. Due to advances in technological research, many medical applications that use 3d objects are being developed to assist specialists. With the aim of increasing the physical realism of 3D simulations in this scenario, our approach combines Smooth ...

Modeling and Simulation of Blood Vessel Networks on the Grid

2009 Fifth International Conference on Semantics, Knowledge and Grid, 2009
The simulation of the dynamics of the blood flow in the venous network of the lower limb is an important tool for supporting clinical research and for suggesting possible treatments for many diseases, e.g. for enhancing the surgical treatment of Chronic Venous Insufficiency (CVI). A suitable haemodynamic model of the venous network of lower limbs gives

Multiscale simulations of blood-flow

Proceedings of the 1st Conference of the Extreme Science and Engineering Discovery Environment: Bridging from the eXtreme to the campus and beyond, 2012
We review our recent advances on multiscale modeling of blood flow including blood rheology. We focus on the objectives, methods, computational complexity and overall methodology for simulations at the level of glycocalyx (

Computer simulations of blood pressure tracking

Computer Methods and Programs in Biomedicine, 1988
Individual blood pressures (BP) tend to remain in the same relative position within a population BP distribution ('tracking'). Individuals in the upper range of the distribution may be predisposed to future hypertension, but this has not been proven epidemiologically.

Simulation of blood bank systems

ACM SIGSIM Simulation Digest, 1979
This paper examines the use of simulations to develop decision procedures for the management of individual hospital blood banks and central blood bank systems. Due to the perishability of blood products and the stochastic nature of both the demand and supply processes, such multi-product, multiechelon systems can only be analyzed effectively by ...

Effects of simulated microgravity (HDT) on blood fluidity

Journal of Applied Physiology, 1992
Exposures to microgravity and head-down tilt (HDT) produce similar changes in body fluid. This causes an increase in hematocrit that significantly affects hemorheological values. Lack of physical stimulation under bed rest conditions and the relative immobility of the crew during spaceflight also affects the blood fluidity. A group of six healthy male

Blood vessel modelling and simulation of the blood flow

2014
The blood vessels is an important part of the human body. Every year, thousands of people die because of the vessel related diseases. The modelling and simulation of blood vessels can help people understand these diseases better. The aim of this project is to find the processes involved in computational fluid dynamics using OpenFOAM and create ...
