Treated as a 2-phase flow,the blood flow in the left coronary artery with stenosis was transiently simulated with the method of computational fluid mechanics,under the bidirectional fluidstructure interaction between the blood flow and the vascular wall.The blood flow distribution characteristics in the left coronary artery was analyzed at typical moments within a cardiac cycle,and the effects of the 2-phase blood model plus the fluid-structure interaction on the hemodynamics were studied in comparison with...
