A: Model representation of a thrombus consisting of a nonpermeable core of radius and a fibrin cap of thickness , where is the radius of the thrombus.

Flow is uniform at infinity. B,C: Velocity field near the thrombus (, ) with low (B) () and high (C) () permeable fibrin cap, the flow Reynolds number, . The flow at infinity is along the horizontal axis. Color scale shows the relative absolute velocity .
