Abstract
The magnetic field perturbation in a magnetic fluid with pulsating air bubbles is a phenomenon providing information on the size of bubbles and on features of the bubbles’ evolution under the influence of a non-uniform magnetic field. A research was carried out with six samples of nanodispersed magnetic fluid, which were produced using carrier fluids with different viscosities. A large experimental database has been collected, which made it possible to plot histograms of the bubble size distribution. The dependence of parameters, characterizing the process of bubble generation, on the magnetic fluid viscosity was determined. The effect of the magnetic field perturbation in a magnetic fluid with pulsating bubbles can be used to develop a fundamentally new method of balanced gas supply into the reactor as well as to study the magnetic fluid boiling process.
