Abstract

An improved electro hydrodynamic method is provided. The method comprises arranging (11) an electro hydrodynamic device inside an enclosure and distributing (12) positive and/or negative ions inside the enclosure during a charging period with a certain defined amount of power. The distribution of the positive and/or the negative ions inside the enclosure (20) is performed so that a predefined amount of charge is set on the interior of the enclosure (20). Within a predetermined period of time after the charging period has ended, the electrospinning device is activated so as to create a product. Finally, the product is removed from the device. The present invention offers a solution for the problem of non-identical initial process conditions for an electro hydrodynamic process caused by any electric charges on the equipment.
