The stability of a non-isothermal circular Couette flow is analyzed when subjected to a dielectrophoretic force field. Outward and inward heating configurations are considered when the inner cylinder is rotating and the outer cylinder is at rest. In addition, an alternating voltage is applied between the two cylinders to induce a radial electric buoyancy that acts on the dielectric fluid. The linear stability analysis provides the threshold for the first transition to instability, as well as the corresponding wavenumber and frequency of the modes. This article is part of the theme issue 'Taylor-Couette and related flows on the centennial of Taylor's seminal paper (part 1)'.
当受到介电泳力场作用时，对非等温圆形库埃特流的稳定性进行了分析。在内圆柱旋转而外圆柱静止的情况下，考虑了向外和向内加热配置。此外，在两个圆柱之间施加交流电压以诱导作用于介电流体的径向电浮力。线性稳定性分析给出了首次转变为不稳定状态的阈值，以及相应的模式波数和频率。本文是主题为“泰勒开创性论文发表一百周年之际的泰勒-库埃特及相关流动（第1部分）”的一部分。
