Enhancing mass transfer results in efficiency increment and reduction in time period of transfer. On the other hand increasing mass transfer can occurs either active or inactive. In active method, external forces such as electric and magnetic forces causes enhancement in mass transfer intensity. However, in inactive method alteration of geometry of group like grooving the surface results in increment in transfer intensity. Electro-hydrodynamic method is an active method consumes less energy in comparison with traditional methods. In this method the electric field is coupled with the fluid field in the dielectric environment of fluid by applying an extra volume force as result of applied field. In this method both the high voltage fields and direct low intensity as well as indirect can be applied to dielectric fluid between positive and negative electrodes. Researches show that there will be a 200 to 500 percent of increment in transfer intensity if the electro-hydrodynamic method is used. In this work the equations of drying procedure are studied under the effect of electro-hydrodynamic. After derivation of equations by considering the geometry of the problem the appropriate boundary conditions have been chosen. After solving the equations and validation of results by comparing with experimental data, analyses of sensitivity of the model by alteration of the effective parameters that can affect the dependent variable such as applied voltage, environment temperature, velocity of entrance air, distance between electrode and surface and the time have been done. By analyses of sensitivity and the effect of parameters alteration the model has been optimized for our problem’s conditions. The modeling results show that increasing the applied voltage results in decrement of time of equilibrium moisture. So that with 10 millimeter of distance between electrode and surface without air entrance in 60 degrees of Celsius and 8000 volt as the maximum value of voltage, the equilibrium moisture with the environment will occur after 520 minutes. In a constant value of voltage, velocity and temperature of the air, decreasing distance between electrode and surface causes 7.2 times decrement in equilibrium moisture time period. Velocity of entrance air only in developed model reduces the drying time. Average of undeveloped velocity with electric field was elimination of Corona. The maximum value of velocity to 2 meter per second in different voltages results in increment of average velocity and in higher velocities by decreasing the Corona’s velocity presented negative effects. Increasing the temperature of the air also causes increment of drying intensity from the surface as well as decreasing the equilibrium moisture time period. Increasing temperature from 30 degrees to 40 and the 50 degrees of Celsius has a clear effect on drying time but increasing temperature beyond 50 degrees of Celsius does not affect the drying time so much.
