Using a New Capillary Viscometer to Study the Viscosity of Magnetic Fluid Systems
The authors study the viscosity of liquids using a capillary viscometer of their own design. A value of viscosity is determined by the drop in pressure in the capillary, which makes it possible to study optically opaque liquids and carry out measurements in a magnetic field. A series of calibration experiments are carried out on liquids with known values of viscosity. The obtained dependences of the magnetoviscous effect in magnetic fluid samples with different structures and physical parameters are consistent with known theoretical and experimental data.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
