Mechanical properties of smart fluids under combined electrical and magnetic fields

Abstract

This paper presents the results of experimental in-vestigation of mechanical properties of magnetoelectro-heological fluids – the media which respond to both elec-trical and magnetic fields. The investigated materials show the synergistic effect for many compositions – the shear stress increase induced under combined action of electrical and magnetic fields is larger than the sum of the incre-ments induced separately by the electrical and magnetic fields. The possibility of the property control using two independent physical channels will allow applying these media in many devices and technologies (heat exchangers, hydraulic systems, vibrodamping devices, etc.).
