Investigation of Blood-Like Non-Newtonian Fluid Flow in Stenotic Arteries using the Lattice Boltzmann Method in 2D
Original language description
Abstract The impact of non-Newtonian fluid properties on the mathematical modeling of flow in stenosed arteries is investigated. The main goal is to determine whether the Newtonian fluid model is sufficient for the flow modeling in the desired geometry. The magnitude of negative horizontal flux is used as a primary quantity for comparing Newtonian and non-Newtonian approaches. The comparison is performed for vessel geometries with gradually increasing severity of stenosis. The mathematical model is solved using the lattice Boltzmann method with a modification to include the non-Newtonian effects. The results show that the difference in fluid characteristics increases with the degree of stenosis. However, for the simulation of flow in the least stenosed artery, both models provide similar results and, thus, the Newtonian model can be employed.
