Analysis of the Casson and Carreau-Yasuda non-Newtonian blood models in steady and oscillatory flows using the lattice Boltzmann method
J. Boyd,James Buick,Simon Green +2 more
TL;DR: It is found that compared to analogous Newtonian flows, both the Casson and Carreau-Yasuda flows exhibit significant differences in the steady flow situation, which may be important for the study of atherosclerotic progression.
A second-order accurate lattice Boltzmann non-Newtonian flow model
J. Boyd,James Buick,Simon Green +2 more
TL;DR: In this article, a second-order accurate lattice Boltzmann model is presented for non-Newtonian flow, which is implemented using a power law model to enable the accuracy of the model to be assessed.
Application of the lattice Boltzmann model to simulated stenosis growth in a two-dimensional carotid artery
TL;DR: The lattice Boltzmann model is used to observe changes in the velocity flow and shear stress in a carotid artery model during a simulated stenosis growth, suggesting that atherosclerotic plaque build-up creates regions of flow with properties that favour atherosclerosis progression.
Application of the lattice Boltzmann method to arterial flow simulation: investigation of boundary conditions for complex arterial geometries.
TL;DR: The results indicate that the extrapolation scheme is preferable in narrow arteries, or when a stenosis is present in a larger artery, when the importance of the boundary conditions is considered.

Three-dimensional modelling of the human carotid artery using the lattice Boltzmann method: I. Model and velocity analysis
J. Boyd,James Buick +1 more
TL;DR: It is found that the three-dimensional model agrees well with previous literature results for carotid artery flow, and the velocity fields in the body of the fluid are analysed at six times of interest during a physiologically accurate velocity waveform.
