The paper presents the results of theoretical and experimental studies of thermal convection in a rotating horizontal cylindrical liquid layer. A layer with boundaries of different temperatures both when heating from inside and outside is considered. Steady thermal convection is determined by two mechanisms: thermovibrational and centrifugal ones. The first one appears due to oscillations of nonisothermal liquid in the cavity frame caused by gravity. Both mechanisms manifest themselves in the formation of two-dimensional convective rolls, extended along the axis of rotation. It is shown that the results of the experimental study of the layer quasiequilibrium stability are in a good agreement with the results obtained in the framework of numerical calculation and linear theory. The structure of thermal convection and heat transport in the supercritical area of parameters is studied numerically, taking into account the slow azimuthal drift of the entire liquid layer in the direction opposite to the rotation of the cavity. The results of numerical simulation and experimental studies are consistent in the area of moderate and large values of the dimensionless velocity of rotation.

本文介绍了旋转水平圆柱形液体层中热对流的理论和实验研究结果。当从内部和外部加热时，考虑具有不同温度边界的层。稳定的热对流取决于两种机制：热振动和离心机制。第一个出现是由于重力引起的空腔框架中非等温液体的振荡。两种机制都表现为沿旋转轴延伸的二维对流辊。结果表明，层准平衡稳定性的实验研究结果与数值计算和线性理论框架下的结果吻合良好。考虑到整个液体层沿与腔体旋转方向相反的缓慢方位角漂移，对参数超临界区域中的热对流和热传输结构进行了数值研究。数值模拟和实验研究的结果在中等和较大的无量纲旋转速度值区域中是一致的。
