Flow structure beneath periodic waves with constant vorticity under normal electric fields

Waves with constant vorticity and electrohydrodynamics flows are two topics in fluid dynamics that have attracted much attention from scientists for both the mathematical challenge their industrial applications. Coupling of electric fields is significant research interest. In this paper, we study flow structure steady periodic traveling waves on a dielectric under effect normal fields. Through conformal mapping technique combined pseudo-spectral numerical methods, develop an approach allows us to conclude can zero, two, or three stagnation points according variations voltage potential. We describe detail recirculation zones emerge together points. addition, show number local maxima pressure bottom boundary intrinsically connected saddle
