“…Therefore, condition [37] is replaced by condition [42]. Using the boundary conditions [34]- [36] and [42], the solution of Laplace equation [7] yields another profile for the distribution of the electric potential φ 1 as given in the Appendix. Accordingly, Eq.…”

“…The electric conditions that have to be satisfied at y = ±a are condition (20) and condition (21). With these boundary conditions, the solution of the Laplace equation (28) yields the distribution of the potential field φ 1 in the three layers, as given in Appendix A.…”

“…Furthermore, the viscosity affects the surface charge density. El-Dib [21] has extended the nonlinear stability of charged interfaces between two inviscid fluids studied by Mohamed and Elshehawey [22] in order to study the impact of the relation between the viscosity force and the surface charges density through nonlinear analysis of viscous flow. He considered the same approach for weak viscous forces, as demonstrated in [19].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
