Effects of mixed electric field on characterization ofelectrohydrodynamics drying system

In this paper, we present a new structure of applying two electrical power supplies to generate ionic wind. inthis configuration, two power supplies were applied simultaneously with a modulated voltage to an electrohydrodynamic(ehd) system then corona discharge parameters and ehd thrust characterization was investigatedby a corona dryer mechanism. the ehd thrust experiments were performed with a pin to plate and sdbdarrangements. the results show that with the simultaneous application of two power supplies the drying ratein a drop of water as a standard sample was greatly enhanced and the drying time was reduced. thus, thetotal evaporation was occurred in 1 minute in the sdbd structure with a power of 7 watts and in 1.5 minutes inpin to plate structure with a power of 2.5 watts. eventually, it was observed that the use of mixed electric fieldsenhances the ionic wind, hence increases the non-thermal evaporation process significantly. furthermore, thedrying rate has grown notably in sdbd configuration.
