Ratio of adhered PLT<br />

a simplification used is that only a single platelet can be detached.<br />

5. Result and Discussion<br />

Our model capability to capture the aggregation of platelets is shown in Fig.1. It is vivid<br />

in some snapshots that the drag-dependent detachment function played very crucial role<br />

in adapting the aggregation to flow regime. The Fig.1 can show mountain-like structure<br />

of the aggregated platelets which was observed in in-vivo experiment of [12].<br />

Fig.1; snapshots of aggregation of platelets; there are detachments between picture C and D.<br />

The rate of adhesion, as can be seen in Fig.2, is constant in 60 seconds of simulation. It<br />

is comparable with the previous study of Pivkin [6] and Goodmann et al. [13].<br />
