Fig. 4.

Contour plots displaying wall shear rate calculations along the (iv) orange line of Fig. 2(b) for the (a) low and (b) high PIV magnifications. Positive shear is a result of flow in the clockwise direction, with negative shear caused by flow in the counterclockwise direction. The shear rate was normalized over 500 s⁻¹ to observe areas between −1 and 1 that are prone to thrombus deposition.
