Abstract

Abstract: We applied a modified unsteady two-phase flow model for the first time to describe the hemodynamic and thermal behaviors of flow in a realistic bifurcation structure incorporated with flexibility phenomena. A current-carrying wire magnetic field was introduced vertically nearby the flexible vessel to determine the effect of the interaction between flowing nanofluid (blood and 3% ( w / v ) Fe3 O4 ) and flexible wall. The pressure and vorticity profiles along the flexible segment, as well as the velocity and temperature of fluid taking at the middle line of the collapsible vessel were analyzed during move-up or move-down of the flexible arterial wall. The results reveal that the profiles of pressure and vorticity are increased and decreased respectively for different current intensities. Also, the effect of the magnetic field with different current intensities moves the elastic vessel wall outwardly that leads to the resistance on the flow field considerably. Thus, the current-carrying wire magnetic field can shift the local maximum velocity toward the flexible vessel wall. These results can be beneficial for curing the vascular clogging of vessel based nano-drug delivery system. Highlights: We developed a modified unsteady two-phase flow model with a collapsible bifurcated arterial network. Dynamic mesh based a novel iteration procedure was utilized to solve the coupled fluid-membrane model. Application of magnetic source namely a current-carrying wire is crucial to analyze the flexible phenomena.
