3D‐Printed Electrohydrodynamic Pump and Development of Anti‐Swelling Organohydrogel for Soft Robotics

Advanced Materials, Volume 37, Issue 7, February 19, 2025.
This study advances electrohydrodynamic (EHD) pumps by introducing a 3D‐printable anti‐swelling organohydrogel for soft robotics. Using digital light processing (DLP) technology, precise components are fabricated, resulting in a pump with 90.2 kPa pressure and 800 mL min−1 flow rate.

Development and Application of One‐Sided Piezoelectric Actuating Micropump

Smart Materials Research, Volume 2013, Issue 1, 2013., 2013
Three types of one‐sided actuating piezoelectric micropumps are studied in this paper. In the first type, one‐sided actuating micropump with two check valves can enhance the flow rate and prevent the back flow in suction mode to keep the flow in one direction.

Modeling of fluid‐rigid body interaction in an electrically conducting fluid

GAMM-Mitteilungen, Volume 47, Issue 3, September 2024.
Abstract We derive a mathematical model for the motion of several insulating rigid bodies through an electrically conducting fluid. Starting from a universal model describing this phenomenon in generality, we elaborate (simplifying) physical assumptions under which a mathematical analysis of the model becomes feasible.

A numerical model of the VKS experiment

, 2009
We present numerical simulations of the magnetic field generated by the flow of liquid sodium driven by two counter-rotating impellers (VKS experiment). Using a dynamo kinematic code in cylindrical geometry, it is shown that different magnetic modes can ...

Converging cylindrical magnetohydrodynamic shock collapse onto a power-law-varying line current [PDF]

, 2016
We investigate the convergence behaviour of a cylindrical, fast magnetohydrodynamic (MHD) shock wave in a neutrally ionized gas collapsing onto an axial line current that generates a power law in time, azimuthal magnetic field.
