Nonlinear waves in a viscous horizontal film in the presence of an electric field

摘要: Abstract In this work, we consider the influence of non-conservative forces in propagation weakly nonlinear waves on surface a shallow viscous perfectly conducting liquid layer stressed by normal electric field. We introduce losses at bottom solving boundary equations for velocity. derive an integro-differential equation deflection interface. To prevent decay waves, discuss possibility sustaining them through external input electrical energy. For ohmic there appear tangential interfacial stresses that could pull liquid. perform energy balance system and deduce order magnitude fields needed to maintain these waves.
