This paper presents the results of an investigation of the electrohydrodynamic augmentation of drying under forced convection. Heat and mass transfer coefficients were calculated from the drying rates of sponges, using the analogy between heat and mass transfer. The test setup used was a flat plate with tangential air flow. Electrical forces, used to disturb the boundary layer, were applied by placing a high-voltage electrode above the sponge which was maintained at ground potential. Augmented heat and mass transfer coefficients were correlated to nondimensional terms developed from similarity and modeling principles.
