摘要

摘要研究了在水平电容器的交变电场中导电不良流体的电热对流。根据电导电荷形成机制框架内的五模态模型，研究了失重状态下低频电场的电对流非线性状态。发现在两种不同的同步和亚谐波状态之间存在着滞后过渡。向混沌的过渡是通过间歇或次谐波级联发生的。

Nonlinear Regimes of Electric Convection of Poorly Conducting Fluids in Weightlessness at Low Frequencies of an Electric Field

Electrothermal convection in a poorly conducting fluid in an alternating electric field of a horizontal capacitor is studied. The nonlinear regimes of electric convection in weightlessness are studies at low frequencies of the electric field on the basis of the pentamodal model within the framework of the electroconductive charge formation mechanism. Hysteresis transitions between two different synchronous and subharmonic regimes are found to exist. Transitions to chaos occur by means of either interemittance or a subharmonic cascade.

期刊介绍： Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
