Numerical studies on shock cell interaction
In this paper, the behavior of a red blood cell under shock impacts has been studied with numerical simulations. Two types of shock wave are considered: one is the planar shock wave and the other is the shock wave induced by bubble collapse. The results show that the bubble induced shock impact is able to cause considerable cell rupture (haemolysis) but the planar shock can only makes several order less strain than the critical value. Furthermore, the roles of the difference viscosity between the blood and cytoplasma seems to play major role for the strain increase after the planar shock passes through the red blood cell.
