Abstract
Two-dimensional wave electroconvective flows and transient processes in a low conducting nonisothermal liquid filling a parallel-plate horizontal capacitor, which emerge due to the action of a steady electric field and the charge injected from the cathode, are simulated numerically. The dependences of the wave flow characteristics (stream function amplitude, oscillation frequency at a fixed point of the convective cell, and phase velocity of the wave) on the heating intensity and the electric field strength are obtained. The bifurcation diagrams and the stable wave solution map are constructed. The behavior of trajectories on the world line plot and the evolution of spatial harmonics are analyzed for the process of transition from the standing wave regime to the traveling wave regime.
