Abstract: A method for altering one or more properties of a dielectric fluid for use in an electrohydrodynamic, EHD, thermal management system (100), as well as the system, are provided. The system comprises at least one EHD pump unit (110) comprising at least two electrodes for pumping the dielectric fluid and at least one enclosure (120) for accommodating the fluid within the system. The method comprises exposing the dielectric fluid to an ionizing process (122) configured to ionize the dielectric fluid, and operating the pump unit to circulate the exposed fluid in the enclosure.

Abstract: A fluidic device is disclosed, comprising an enclosed passage that is adapted to convey a circulating fluid. The enclosed passage comprises a flow unit having a first electrode and a second electrode offset from the first electrode in a downstream direction of a flow of the circulating fluid. The first electrode is formed as a grid structure and arranged to allow the circulating fluid to flow through the first electrode. The fluidic device may be used for controlling or regulating the flow of the fluid circulating in the enclosed passage, and thereby act as a valve opening, reducing or even closing the passage.

Abstract: An array (10) of flow units (100) for controlling a flow of a fluid is disclosed. The flow units (100) are arranged to have a lateral extension in a common lateral plane and such that a downstream side (D) of a first one the flow units is in fluid communication with an upstream side (U) of a second one of the flow units so as to allow a flow of fluid to pass through said flow units. The flow units comprise a first electrode (110) and a second electrode (120) which are connectable to a voltage source. At least a portion of the first electrode has a maximum height (h1) in a direction parallel to the direction of the flow and a maximum gauge (w1) in a direction orthogonal to the direction of the flow, wherein said maximum height is larger than said maximum gauge so as to improve the pumping efficiency of the device. A method for controlling a fluid flow by means of such device is also disclosed.
