Annotation
In this article, for the first time were obtained experimental data on the effects of ferromagnetic nanopowders to the thermal diffusivity of transformer oil. A brief review of the experimental setup and the experiment itself to study the thermal conductivity of magnetic fluids based on transformer oil using laser flash in the magnetic field induction interval (1.6–3.9) * 10-2mTl depending on the pressure of P = 0.101-0.141 MPa at room temperature. At the same time, the thermal conductivity of the sample was calculated by solving a one-dimensional nonstationary linear equation. It is noted that the developed experimental facilities can be used to quickly determine the thermal conductivity of liquids depending on the pressure and magnetic field in laboratory conditions.
Key words
