Analytically Study the Ferrohydrostatic Pressure with FHD Bernoulli Theory
The ferrohydrostatic pressure is an important magnetization characteristic for the ferro-fluid used as the working medium of shock absorber or as a leak-proof dynamics seal of rotating shaft. To generalize and analyze the experimental results, an analytic formulation of magnetic pressure derived from the Ferrohydrodynamics (FHD) Bernoulli theory is constituted. Meantime, an auxiliary testing mechanism on the magnetic levitation, features as an easy, economical and efficient utility, is then set up in this study and which is quit different from the expensive cost required in precise VSM measurement system. While compared with above results, a good agreement will be accessed within the working interval of magnetic flux 0 ~ 60 mT.
