Enhanced discrete phase model for multiphase flow simulation of blood flow with high shear stress
Science Progress, 2021 Shear stress is often present in the blood flow within blood-contacting devices, which is the leading cause of hemolysis. However, the simulation method for blood flow with shear stress is still not perfect, especially the multiphase flow model and ...

Optimal control in blood flow simulations [PDF]
International Journal of Non-Linear Mechanics, 2014 Abstract Blood flow simulations can be improved by integrating known data into the numerical simulations. Data Assimilation techniques based on a variational approach play an important role in this issue. We propose a non-linear optimal control problem to reconstruct the blood flow profile from partial observations of known data in idealized 2D ...

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021 Results of large eddy simulation of three-dimensional flow in a model of the blood vessel with a one-side 70% stenosis at a Reynolds number of 1800 are presented. The Germano-Lilly model was used for subgrid viscosity evaluation.

Simulation of Mechanical Heart Valve Dysfunction and the Non-Newtonian Blood Model Approach
Applied Bionics and Biomechanics, 2022 The mechanical heart valve (MHV) is commonly used for the treatment of cardiovascular diseases. Nonphysiological hemodynamic in the MHV may cause hemolysis, platelet activation, and an increased risk of thromboembolism.

Particle Dynamics Methods of Blood Flow Simulations [PDF]
Mathematical Modelling of Natural Phenomena, 2011 Summary: Various particle methods are widely used to model dynamics of complex media. In this work molecular dynamics and dissipative particles dynamics are applied to model blood flows composed of plasma and erythrocytes. The properties of the homogeneous particle fluid are studied. Capillary flows with erythrocytes are investigated.

Mesoscopic Blood Flow Simulation Considering Hematocrit-Dependent Viscosity
Journal of Biomechanical Science and Engineering, 2010 Blood is a concentrated suspension of blood cells in plasma. Motion and deformation of red blood cells (RBCs) and their mechanical interaction play important roles in determining blood rheology.

Heart blood flow simulation: a perspective review [PDF]
BioMedical Engineering OnLine, 2016 Cardiovascular disease (CVD), the leading cause of death today, incorporates a wide range of cardiovascular system malfunctions that affect heart functionality. It is believed that the hemodynamic loads exerted on the cardiovascular system, the left ventricle (LV) in particular, are the leading cause of CVD initiation and propagation.
