NUMERICAL SIMULATION STUDY OF THE FLUID–STRUCTURE INTERACTION OF THE ARTERY UNDER PERIODIC EXTERNAL FORCING OF MASSAGE

The impact of vibrating manipulation on arterial hemodynamics and mechanical properties is explored by using the finite element method for the fluid–structure interaction. Numerical simulation results show that massage greatly changes the flow behavior of blood within the artery. Under the massage m...

Description
Summary:The impact of vibrating manipulation on arterial hemodynamics and mechanical properties is explored by using the finite element method for the fluid–structure interaction. Numerical simulation results show that massage greatly changes the flow behavior of blood within the artery. Under the massage manipulation, the mean blood flow increases by more than 5.34% at a frequency of  and by smaller values at frequencies of   and  . The blood flow has obvious disorder characteristics and an obvious wall shear stress concentration in the mixed flow area. The von Mises stress of the artery wall increases, reaching a peak value at the maximum deformation.
