Recommended international standard for dimensionless parameters used in electrohydrodynamics

Modern day electrohydrodynamics (EHD) was defined as an interaction between electrical parameters and fluid flow included multi-phase systems. However, unlike well-established magnetohydrodynamics (MHD), the terminology and dimensionless parameters used for EHD analyses were not. unified. Based on the IEEE-DEIS-EHD technical committee's recommendation, unified dimensionless parameters for EHD studies are proposed in this report.
