摘要: We consider waves on a layer of finite depth governed by the Euler equations in presence gravity, surface tension, and vertical electric fields. use perturbation theory to identify canonical scalings derive Korteweg–de Vries Benjamin-Ono equation arising interfacial electrohydrodynamics. When Bond number is equal 1∕3, dispersion disappears reduces equation. In additional limit vanishing fields, we show how obtain new evolution that contains third- fifth-order as well nonlocal field term.
