A lattice Boltzmann modelling of electrohydrodynamic conduction phenomenon in dielectric liquids

Numerical analysis of electro-convection in dielectric liquids with residual conductivity

“…Meanwhile, both analytical and numerical solutions are performed to discuss the effect of the electric field strength, system geometry, and alternating current (AC) frequency on the velocity and pattern of the aforementioned EHD flow. Furthermore, the electrohydrodynamic flow based on the conduction model attracts the attention of researchers for the application of conduction pumping 3,[27][28][29] . This specific application is expected to be used in many engineering fields, including space thermal control and flexible microscale pumping, due to its advantages of having no mechanical components, no noise, easy miniaturization 30 .…”

Numerical prediction of transient electrohydrodynamic instabilities under an alternating current electric field and unipolar injection

“…The Coulomb force acts on charges and causes the fluid to flow. Owing to its low noise and energy consumption and lack of mechanical movement, EHD technology has unique advantages in active flow control [ 1 ], microchannel transport [ 2 ], heat transfer enhancement [ 3 ], EHD drag pumps [ 4 , 5 ], alternating current (AC)–EHD fluid micromixing and microfluidic systems [ 6 , 7 , 8 ], EHD printing driven by pulsed and AC voltages [ 9 , 10 , 11 ], atomization technology [ 12 ], and so on.…”
