Investigating Schmidt number effects in turbulent electroconvection using one‐dimensional turbulence

Turbulent electroconvection denotes a fluctuating multiphysical flow in which hydrodynamics and electrokinetics interact on multiple scales. The dynamical processes at work are entangled down to the molecular-diffusive scales that determined by Schmidt (Sc) Reynolds (Re) number. Turbulence properties generally nonuniversal leads high numerical resolution requirements. We address challenges associated with accuracy feasibility utilizing stochastic one-dimensional turbulence (ODT) model. Here, ODT is applied turbulent Couette of dilute electrolytes as canonical problem for electroconvection. For Sc ⩾ O(10), predicts an increase skin friction drag due electrohydrodynamically (EHD) enhanced small-scale eddy production once sufficiently turbulent.
