The Quasi-Steady Hypothesis
A number of studies of arterial flows have made the assumption that flow at peak systole (peak flow rate) is similar to steady flow at that flow rate.
Argue that the turbulence time scales are significantly smaller than pulsation time scale.
A number of studies have therefore based their analysis of arterial flows on steady state flow models.
This assumption neglects
- acceleration/deceleration effects
- history effects
