In this paper, assuming that the blood flow is multiphase flow composed of blood plasma and activated fibrinogen, the effects of surface tension near the wall are included in the modified lattice Boltzmann Method (LBM). To predict thrombus formation in every shear stress flied of flow, effects of threshold level of physical parameters such as shear rate, adhesion force (effective distance from the wall) is used for estimation thrombus formation rate. In this model, the most important point is to include the surface tension and adhesion force to the wall by introducing simple parameters such as the material properties of the wall. The new model for predicting thrombus formation by adding surface tension near the wall was proposed and the trend of thrombus's attaching to the wall could be simulated more adequately than in case of previous model
