Abstract

Detailed and accurate evaluation of blood flow through stenotic arteries is important and can provide better clinical care for patients. Lattice Boltzmann method (LBM) represents an alternative approach to study blood flow and the main goal of this study is to validate its accuracy against traditional CFD methods. The validation was performed for blood flow through complex geometries of coronary arteries, by comparing the results with traditional CFD methods. The good agreement of results demonstrates that LBM can be considered as an efficient alternative that can produce fast results of the same quality as traditional CFD methods.
