Numerical simulation of pulsatile blood flow: a study with normal artery, and arteries with single and multiple stenosis

Abstract Numerical simulations of pulsatile transitional blood flow through symmetric stenosed arteries with different area reductions were performed to investigate the behavior of the blood. Simulations were carried out through Reynolds averaged Navier-Stokes equations and well-known k-ω model was...
