Figure 2.
Plot of the distances translated in the x-, y- and z-direction in each timestep of 0.1 s by a platelet undergoing Brownian motion near a surface in a quiescent fluid of viscosity 1 cP in the Stokes regime of flow. Fluctuations in platelet position with respect to its previous position are shown for a period of 5 seconds for (a) an initial platelet centroid height of 3.0 μm and (b) an initial platelet centroid height of 1.5 μm. The average velocities in each direction over the 5 second interval are listed in each plot.
