Oscillating shear index, time averaged wall shear index, relative residence time analysis in 3D structured analytical artery
This study investigates the bio-mechanics of one main artery model in a three dimensional analytical cylindrical generated geometry based on a real human artery. Structured geometry is a medium large (celiac) artery. Constant and sinus velocity profile is applied as an interpolated input. Non-Newtonian Carreau viscosity model and fluid-structure interaction (FSI) is applied numerically. Oscillating Shear Index (OSI), Time Averaged Wall Shear Stress Index (TAWSSI) and Relative Residence Time (RRE) as well as velocity, pressure and pressure are studied. As an example, stenosed areas can be studied with the help of the model. Then these values are compared and presented for their importance.
