Abstract

Abstract In this paper we investigated from rheological point of view some samples of ferrofluid-based magnetorheological fluids (FF-MRFs) with different volumic fractions of Fe microparticles, but with the same ferrofluid used as carrier liquid. We correlated the dimensionless flow curves, measured at different values of the magnetic field induction, using either Mason number or Casson number. It has been shown that in this approach, data sets measured under different conditions collapse on a single curve. This master curve is useful for controlling the concentration of Fe particles, so that the magnetic and magnetorheological properties of FF-MRF to be adapted to obtain high-performance applications.
铁磁流体基磁流变流体流变特性的无量纲数相关性研究
摘要本文从流变学的角度研究了以同一铁磁流体为载液,含不同体积分数铁微粒的铁磁流体基磁流变液(FF-MRFs)样品。我们用梅森数或卡森数将在不同磁场感应值下测量的无量纲流动曲线关联起来。已经证明,在这种方法中,在不同条件下测量的数据集在一条曲线上崩溃。该主曲线可用于控制铁颗粒的浓度,从而适应FF-MRF的磁性和磁流变特性,以获得高性能的应用。
