“…The good agreement is achieved due to SMICFoam (Rohlfs et al 2017), which uses a limiter of artificial interface compression. The model of reduced dimensionality is closely related to WIBL models developed by Wray et al (2017) with the first-order formulations of the electrostatic forces and zero surface charges. Contrary to the leaky dielectric case studied by Wray et al (2017), the surface forces acting on a perfectly dielectric liquid are always of destabilizing character.…”

“…Note, it is shown later in comparison to full numerical simulations that the first-order approximation is well suited to describing the effect of the electric field. For higher-order approximations of the electric field, also taking into account tangential stresses and surface charges, the reader is referred to the work of Wray et al (2017). Figure 1 illustrates the one-dimensional case where a liquid column with heighth is located between two capacitor plates of distanceH c .…”

“…The regularising effect of dispersion for the non-electrified gKS equation was analysed in detailed by Chang et al (1995) and . Recently Wray et al (2017) have derived a fully nonlinear model for an electrified falling film which is valid at finite Reynolds number using a weighted residuals approach. We note that most previous studies have focused on acute inclination angles.…”

“…Explicit computation of the a n (and their corresponding basis functions) A. W. Wray and R. Cimpeanu can be avoided by a suitable choice of weighting function w. This weight is the solution of the adjoint of the leading-order problem, and hence depends on the problem being solved, including its geometry (Ruyer-Quil et al 2008). For viscous flow on a rotating disk, this weight is (Wray et al 2017b)…”
