3D printing-assistant method for magneto-active pulse pump: Experiment, simulation, and deformation theory

Applied Physics Letters, Volume 117, Issue 24, December 2020. This Letter reports a magneto-active pulse pump (MAPP) consisting of a flexible check valve and a magneto-active pipe developed by using a 3D printing-assistant method. The deformation behavior of the magneto-active pipe is investigated by using the three-dimensional reconstruction, simulation, and theoretical analysis. The larger deformation under a high magnetic field produces higher driving pressure, and thus, the MAPP can be used to transfer liquid. It is found that the MAPP responds to the strength and frequency of the magnetic field simultaneously and the pumping performance can be analyzed by a magneto-fluid-solid coupling simulation. This work provides guidance for the design and manufacture of pulse pumps in future heart pump components.
