Table 2.

Results from simulations with periodic sinusoidal wall motion (60 < R < 120) and skewed sinusoidal wall motion (40 < R < 60), both with the same time period (T=3.2 s) and unsteady inlet velocities. Differences between axial wall shear stress and Poiseuille were averaged over time for these unsteady cases
