A Taylor-Couette experimental setup for solid-state media

Abstract

The invention discloses a Taylor-Courte experimental device for solid media, which relates to the field of continuum mechanics. The device comprises a cylindrical sample chamber composed of inner and outer cylindrical walls and two annular end faces; and a driving sample The drive mechanism for the relative rotation of the inner and outer cylindrical walls; the torque sensor recording system for recording the relative rotational torque of the inner and outer cylindrical walls of the sample chamber; it also includes a pressurization mechanism that provides axial pressure to the end of the sample in the cylindrical sample chamber; records the sample The pressure sensing recording system for the axial pressure on the end; the information acquisition system for recording the rheological conditions of the solid medium of the sample. The device has a simple structure and is easy to implement, and can extend the research of the rheological behavior of the liquid medium to the rheological research of the solid medium from the classical Taylor-Couette device.

Description

technical field [0001] The invention relates to the field of continuum mechanics, in particular to a Taylor-Courte experimental device for solid medium to test the rheological behavior of solid medium under the action of external force. Background technique [0002] In 1890, Couette first designed a cylindrical device rotating around a concentric axis to measure the viscosity coefficient of fluids, mainly liquids. Then in 1923, Taylor used this device in [Taylor G.I.Stability of a viscous liquid contained between two rotating cylinders.Philosophical Transactions of the Royal Society of London.1923(223):289-343.] to study the problem of fluid stability . Since then, the device has been named after the two scientists. The schematic diagram of the Taylor-Coulter device is shown in figure 1 shown. [0003] Fill the cylindrical sample chamber between the inner wall and the outer wall with experimental liquid (liquid medium). When the inner and outer walls rotate relative to e...

Problems solved by technology

In this way, without using a solid separator, it is impossible to divide the liquid region into two or more different components in the radial direction or / and circumference as the experiment expects, or to divide the same liquid into two or more different colors. area for experiments

However, if a solid spacer is used, the Taylor-Courette rheological experiment of the liquid medium in the original sense cannot be realized.
