  • Patent number: 10695729
    Abstract: Viscosity and other properties are determined at desired temperatures in drilling mud and other fluids by using a versatile cavitation device which, operating in the cavitation mode, mixes and heats the fluid to a specified temperature, and, operating in the shear mode, acts as a spindle for application of Couette principles to determine viscosity as a function of shear stress and shear rate. The invention obviates the practice of adjusting rheology of a drilling fluid by passing it through the drill bit. Drilling fluid may be managed by a “straight-through” method to the well, or by placing the cavitation device in a loop which isolates an aliquot of known volume and circulating the fluid through the loop including the cavitation device.

  • Patent number: 10222056
    Abstract: The apparatus described herein uses a disc wafer-type rotor featuring channels disposed around its circumference and around the interior circumference of the rotor housing specifically to induce cavitation. The channels are shaped to control the size, oscillation, composition, duration, and implosion of the cavitation bubbles. The rotor is attached to a shaft which is driven by external power means. Fluid pumped into the device is subjected to the relative motion between the rotor and the device housing, and exits the device at increased temperature. The device is thermodynamically highly efficient, despite the structural and mechanical simplicity of the apparatus. Such devices accordingly provide efficient, simple, inexpensive, and reliable sources of distilled potable water for residential, commercial, and industrial use, as well as the separation and evaporation of other liquids.

  • Patent number: 9599366
    Abstract: A flameless heater produces hot dry air utilizing hydraulic heat-transfer fluid as a heat transfer medium. The heater is powered preferably by a natural gas engine. The process begins with the natural gas engine producing rotary power which drives a hydraulic pump which directs the heat-transferring fluid through a dynamic heat generator to heat the fluid via an internal friction process. The heated fluid is subsequently circulated through a heat exchanger where a hydraulically-powered fan blows ambient air through to be heated. The heat exchanger also extracts heat from the exhaust and coolant system portions of the engine to further heat the air. The produced dry hot air may be used for general heating. It is envisioned that engines which utilize other fuel sources such as diesel, gasoline, steam, or the like could be utilized with equal effectiveness.

  • Patent number: 9091249
    Abstract: An integrated cooling and climate control system for an offshore wind turbine featuring a reservoir having first and second chambers located in an upper region of the tower.

The cooled coolant fluid is then distributed back to the reservoir. The reservoir has a hollow center and is positioned on a platform having a hollow center. The inlet and outlet pipes of the upper cooling circuit freely hang inside the reservoir chambers so that they may be displaced as the nacelle yaws in order to maintain sufficient circulation of the coolant fluid in the upper cooling circuit. In jacket foundation configurations, the tubular support structures may serve as the lower cooling circuit pipes.

  • Publication number: 20090235914
    Abstract: A heating apparatus and a system that utilize friction to generate thermal energy. The heating apparatus comprises a housing unit, a plurality of heating chambers for generating heat, an actuating unit, a shaft; and at least one blade unit. Each heating chamber comprises a stationary disc member, a rotating disc member, and a medium disposed between the stationary disc member and the rotating disc member. The actuating unit drives the rotating disc member in the heating chamber to generate thermal energy by friction among the stationary disc member, the rotating disc member, and the medium. Thermal energy generation is controlled by rotating speed, diameter of the disc member, and contact pressure between the rotating disc member and the stationary disc member. Tube members can also be used in the heating chambers.

  • Publication number: 20090056645
    Abstract: Aqueous fluids are heated or boiled in a tank or vessel by causing cavitation in the fluid within the tank or vessel. A rotor having cavities on its cylindrical surface is rotated within a closely dimensioned housing submerged in the fluid, deliberately causing cavitation which heats the aqueous fluid without the use of flame or heat exchange surface. An electric motor which powers the rotor may itself be submerged in the tank or boiler vessel. The rotor includes radial channels for imparting centrifugal impetus to the fluid as it flows toward the cavitation zone.

  • Patent number: 6959668
    Abstract: A method and steam generator includes a steam generator container having a heated wall surface, an inlet for a liquid and an outlet for removing the vaporized liquid or steam, a rotor, which is mounted for rotation in the container and causes a rotational flow of the liquid outwardly against the heated wall to cause vaporization. During rotation of the rotor, outer edges of the blades of the rotor contact the wall surface to either abrade or wipe deposits, such as lime, from the wall surface.

  • Patent number: 6959669
    Abstract: The apparatus has a housing with a main chamber in which a rotor is situated. A drive shaft drives the rotor about a longitudinal axis of rotation. The housing has a fluid inlet and a fluid outlet, the fluid inlet communicating with an inlet region and a fluid outlet communicating with an exit region. The outer surface of the rotor forms one boundary for the fluid heat generating region and is confronted by the inner surface of the main chamber which is the other boundary. At least one of these surfaces is angularly inclined relative to the axis of rotation of the drive shaft and rotor. By bodily shifting the rotor in a direction along the longitudinal axis, an increase or decrease in the distance between the outer and inner surfaces is possible in order to adjust for wear or to change the degree of shear experienced by the passing fluid.
