Abstract: An electrohydrodynamic conduction liquid pumping system having a vessel configured to contain a liquid therein, a single pair or multi-pairs of electrodes disposed in a circularly spaced apart relationship to each other inside the vessel and configured to be oriented in the liquid. A power supply is coupled to the electrodes and configured to generate electric fields in-between each electrode pair to induce a net radial pumping of the liquid. A heat source is provided to produce heat sufficient to boil and vaporize the liquid while non-vaporized liquid moving toward the heat source prevents over-heating of the heat source. A heat sink is configured to have a operating temperature below the vaporization temperature of the liquid so that contact of the vapor with the heat sink will condense the vapor into a liquid to replenish the liquid supply moving toward the heat source.

Abstract: An electrohydrodynamic conduction liquid pumping system includes a vessel configured to contain a liquid or a liquid/vapor therein. This vessel can be of a elongate conduit configuration, an elongate channel configuration or a liquid enclosure configuration. At least a single pair of electrodes are disposed in a spaced apart relation to each other on the vessel and configured to be oriented in the liquid. A power supply is coupled to the electrodes and operable to generate electric fields in between the pair of electrodes, the electric forces inducing a net liquid movement relative to the vessel. Various electrode designs are embraced within the concept of this invention.

Abstract: An electrode configuration for use in association with a heat transfer member provided in a thermal energy transfer system. Separate multiple electrical conductors are each received on a respective first surface alteration. Each of the multiple conductors is connected to a different terminal of a multiphase alternating power source so that an electric traveling wave moves in a longitudinal direction of the heat transfer member so as to induce pumping of at least the liquid phase in the longitudinal direction to thereby enhance the thermal energy transfer characteristics of the thermal energy transfer system. In a preferred embodiment, the aforementioned heat transfer members are provided inside of an outer conduit.

Abstract: An electrohydrodynamic (EHD) conduction pump is provided for pumping dielectric liquids, and a particular adaptation for mass transport of isothermal and non-isothermal single phase liquids. The EHD conduction pump does not require direct injection of electric charges into the fluid. The EHD conduction pump includes an EHD pumping section and associated connecting tubes with electrodes arranged in series in the pumping section. The electrodes are coupled to a high voltage low current dc power supply. A positive polarity dc voltage is applied to the electrodes. Various electrode configurations may be used, such as three-needle, hollow-tube, or pin-needle electrode configuration.

Abstract: An electrohydrodynamic induction pumping thermal energy transfer system includes an outer conduit and a plurality of inner conduits disposed within the outer conduit. The system also includes a plurality of conductors disposed about a first surface of at least one of the inner conduits. The plurality of conductors is disposed in a spaced apart relationship to each other and extends longitudinally along the inner conduit.

Abstract: A viscometric thermometer is fabricated with two sensing capillaries connected serially in a common fluid flow circuit. The first capillary is immersed in a reference bath of known constant temperature. Pressure differential across the first capillary is measured and the fluid medium flow rate through the common circuit is determined. The second sensor is positioned in the unknown temperature environment and pressure differential across the second capillary is measured. This second capillary pressure differential is combined with the determined flow rate value to further determine the unknown temperature value.
