【 摘 要 】

The electrohydrodynamic stability of a conducting incompressible stratified fluid topping a dielectric fluid layer is studied. The stability of the system is discussed theoretically and numerically. It is found that the normal electric field has a destabilising effect while the increase of the thickness of the layer has a stabilising influence. The special case of the Rayleigh-Taylor instability is also examined.
