# Numerical study on turbulent blood flow in a stenosed artery bifurcation under periodic body acceleration using a modified k-ε model

@inproceedings{Ro2010NumericalSO, title={Numerical study on turbulent blood flow in a stenosed artery bifurcation under periodic body acceleration using a modified k-$\epsilon$ model}, author={Kyoung Chul Ro and Hong Sun Ryou}, year={2010} }

This article describes the numerical investigation of turbulent blood flow in the stenosed artery bifurcation under periodic acceleration of the human body. Numerical analyses for turbulent blood flow were performed for six simulation cases with different magnitude of periodic accelerations using a modified k−ε turbulence model which is considering drag reduction of non-Newtonian fluid. The blood was considered to be a non-Newtonian fluid which is based on the power-law viscosity model. In…
