Ferrohydrodynamic Capillary Convection
Journal of Thermal Science and Engineering Applications, 2018 Abstract In this work, consideration is given to capillary convection on ferrofluids from the concentration gradient induced when a nonhomogeneous magnetic field is applied. It is known that mass transfer along an interface between two fluids can appear due to a gradient of the surface tension in the so-called Marangoni effect (or Gibbs ...

The equations of ferrohydrodynamics: Modeling and numerical methods [PDF]
Mathematical Models and Methods in Applied Sciences, 2016 We discuss the equations describing the motion of ferrofluids subject to an external magnetic field. We concentrate on the model proposed by Rosensweig, provide an appropriate definition for the effective magnetizing field, and explain the simplifications behind this definition.

A low-frequency ferrohydrodynamic pump for a magneto-caloric refrigerator
Applied Energy, 2023 Ferrohydrodynamic or magnetic pumping enables the design of a magnetocaloric refrigerator with no moving parts. Existing magnetic pumps utilize travelling wave magnetic fields with frequencies in the range of 100 to 1000 Hz. Such high frequencies when utilized in the proposed refrigerator could cause heating which is detrimental to its performance ...

Ferrofluid‐based electrical machines: Conceptualization and experimental evaluation
The Journal of Engineering, Volume 2024, Issue 7, July 2024.This paper aims to Introduce a new structure for electric machines that work based on ferrofluids. The operation principle of the proposed structure is presented by applying some modifications to the synchronous reluctance machine’s model. A dynamic‐transient model of FFEM machines along with electrical equivalent circuits is developed.
