Abstract:
Lattice Boltzmann method（LBM） has recently been proved competitive for studying the domain of fluid flow for various physics systems with complex boundary. In this study, the three-dimensional lattice Boltzmann method （LBM） is used to simulate the conditions at an aortic arch, and some flow information about the axial and secondary fluid velocities and the effective wall shear stress in the bend are presented. Finally, the results are analyzed in detail.[著者文摘]
Key words:
