Abstract

Motivated by recent developments in bio-inspired medical engineering microscale pumps, in
the present article a 3-dimensional sequential simulation of a peristaltic micro-pump is
described to provide deeper insight into the hydromechanics of laminar, viscous flow in
peristaltic propulsion. The Carreau and power-law models are employed for non-Newtonian
behavior. The commercial software package ANSYS Fluent is utilized to conduct a numerical
simulation of laminar peristaltic pump fluid dynamics, based on the finite volume method and
steady space laminar solver. Details are provided for the geometric pump design (conducted
with AUTOCAD), pre-processing (meshing) and necessary boundary conditions to simulate
the peristaltic flow within the pump. Extensive visualization of velocity, pressure and vorticity
contours is included. The present simulations provide a benchmark for future comparison with
experimental studies and indeed more advanced numerical simulations with alternative nonNewtonian models. Applications of the study include biomimetic blood flow pumps, blood
dialysis machines, microscale infusion pumps etc.
