These values were normalized with the BFS height, 2.5 mm. The reattachment length of the initial recirculation region was normalized by the step height and marked on the right vertical axis. Error bars represent the SEM and n = 3 for all blood circulation times. (b) The changes in thrombus volume and exposed surface area (SA) with increasing blood circulation time are presented. Error bars represent the SEM and n = 3 for all blood circulation times. Figure Legend:

Velocity contours are shown to illustrate recirculation regions, and the acrylic model has been outlined in white after the BFS to show the thrombus boundaries. The positions of the slices are indicated with white lines across the WSS distribution on the thrombus surface. A white arrow on each velocity plot denotes the location of the step, and flow is from left to right in all plots. The length scales are different for the velocity and WSS plots. (a) Regions of high WSS are predicted on protrusions from the thrombus surface, even though the entire thrombus is contained within a recirculation region. (b) Location 1 in the velocity plot indicates a portion of the thrombus protruding into the lumen which causes a small recirculation region to develop downstream. This same location in the WSS plot has heightened WSS on the peak followed by a region of very low WSS. Location 2 indicates a recirculation region extending nearly the length of the thrombus, and this corresponds to a strip of low WSS. An example recirculation region has been magnified to provide a better view. (c) Location 3 in the velocity plots indicates a small recirculation region immediately downstream of the step which is reflected as a low WSS region on the upstream portion of the thrombus surface. Location 4 indicates a protrusion that extends far into the lumen of the model. This corresponds to the highest WSS calculated on any of the thrombus surfaces in this study. Location 5 indicates a small recirculation region that forms after this peak and the low WSS region that the CFD predicted at the same location. Figure Legend:

The blood circulation time is displayed in the left column, a side view of the thrombus is presented in the middle column, and a top view of the thrombus is presented in the right column. The asymptotic behavior of both thrombus height and length can be observed qualitatively. The scale bar represents a distance of 5 mm, and the thrombi were formed in flow moving from left to right.

The primary components of the thrombus, red blood cells, and fibrin have been stained a pinkish-red color by H&E. A purple stained nucleus of a white blood cell can also be observed in the slice. Black circles illustrate two surface features (one valley and one protrusion) that are too small to be resolved in this study. Figure Legend:
