Research has progressed from steady flow in circular geometries [5-7]; flow through patient-specific arteries created from medical images [8, 9]; unsteady flow driven by fluctuating pressure waveforms [10] with both Newtonian and non-Newtonian constitutive models for blood viscosity [11-13].
One issue of wind tunnel experiments is the difficulty of simulating unsteady flow conditions like gusts over a useful frequency range [2].
By the comparison of Figures 2-7, we can see that, with the increase of Reynolds number [15, 16], steady flow changes to unsteady flow gradually.
Flow in a tube with an occlusion by using finite difference scheme for steady and unsteady flow is investigated [5].

In rivers with unsteady flow conditions, spur dikes can serve as emerged in ordinary state or submerged during flood.
It is an application that crosses multiple disciplines and requires accurate simulation of both unsteady flow and the transmission of noise and vibration through large complex systems across a broad frequency range," said Phil Shorter, Vice President, CD-adapco.
Two-phase unsteady flow in a pipe where the liquid flows along the bottom and the gas flows above it can reveal different dynamics and flow patterns due to instability and mixing.
Our results showed that as the flow moves through the feeding artery there is acceleration of the blood flow and in the region around the anastomosis the blood experienced significant flow disturbance (swirling and unsteady flow behaviour).
