Methods of experimental study of thermal convection in cavity subject to rotation and vibration

Vibrations of a non-isothermal fluid result in the generation of an averaged flows - "thermal vibrational convection". The effect of vibrations changes qualitatively, and their effectiveness increases significantly under conditions of rotation. This makes vibrations an important tool for controlling the dynamics of non-isothermal systems and the intensification of heat and mass transfer in rotating cavities, which could be useful for optimization of various technological processes. The article describes methods used to study convection in rotating cylinders subject to vibrations. The cases of an annulus with boundaries at different temperatures and a cylinder filled with a heat-generating fluid are discussed. Experimental complex allows one to study thermal convection under the action of various factors, such as rotation, vibrations, librations, orientation of the axis of rotation, inertial waves, and others. •The vibrations of a non-isothermal fluid in a rotating cavity is an effective tool for intensification of heat transport due to the generation of intensive averaged flows•The developed experimental technique and setup provide the investigation of thermal vibrational convection in rotating cavities of various geometries in a wide range of governing dimensionless parameters.
