  • Publication number: 20250164191
    Abstract: Polymeric tube-in-shell heat exchangers with twisted tubes are provided. The heat exchanger may include one or more polymeric tube bundles, wherein each of the one or more polymeric tube bundles includes at least one tube twisted about its length or at least one pair of tubes twisted or wound around each other. The presently disclosed polymeric tube-in-shell heat exchangers with twisted tubes may be especially suited for applications where the use of polymer tubes offers advantages, such as in the case of acid solutions, food and beverage fluids, and carbon capture applications where the use of metal heat exchangers destroy the amines used for capture.

  • Patent number: 8820114
    Abstract: Disclosed herein is a cooling system that utilizes a supersonic cooling cycle. The cooling system includes accelerating a compressible working fluid, and may not require the use of a conventional mechanical pump. The cooling system accelerates the fluid to a velocity equal to or greater than the speed of sound in the compressible fluid selected to be used in the system. A phase change of the fluid due at least in part to a pressure differential cools a working fluid that may be utilized to transfer heat from a heat intensive system.

  • Publication number: 20120260673
    Abstract: Cooling in the supersonic region of a compressible fluid is disclosed. The fluid is accelerated by a reciprocating piston to a velocity equal to or greater than the speed of sound in the fluid in an evaporator. No conventional mechanical pump is required to accelerate the fluid. A phase change of the fluid due to a pressure differential may be utilized to transfer heat from an element to be cooled.

  • Publication number: 20120260676
    Abstract: Cooling via acceleration of a compressible fluid is disclosed. The fluid is accelerated by a rotatable body to a velocity that may be equal to or greater than the speed of sound in the fluid. No conventional mechanical pump is required to accelerate the fluid. A phase change of the fluid may be utilized to transfer heat from an element to be cooled.

  • Publication number: 20120204593
    Abstract: A supersonic cooling system operates by pumping liquid without the need of a condenser. The compression system utilizes a compression wave in the generation of the cooling effect. An inlet of the system may be pulsed to reduce energy required of a pump. The evaporator of compression system operates in the critical flow regime where the pressure one or more evaporator tubes will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

  • Publication number: 20120118538
    Abstract: A method of cooling that accelerates a compressible working fluid without the use of a pump. The method accelerates the fluid to a velocity equal to or greater than the speed of sound in the compressible fluid selected to be used in the method. The fluid is accelerated to a supersonic velocity in a rotating evaporator tube. A phase change of the fluid due to a pressure differential may be utilized to transfer heat from an element to be cooled.

  • Publication number: 20110051549
    Abstract: A central insert causes maximum fluid velocity to shift away from an external tube wall reducing friction losses at the tube wall. Centrifugal forces pull fluid away from a central insert wall minimizing friction at the insert wall. The insert may be used in the context of nozzles, flow tubes, vortex tubes, and other fluid pathways. In a nozzle, grooves may be added to the nozzle wall. By introducing these grooves at the exit or end of a nozzle, nucleation may be improved and cavitation may be triggered prior to a fluid entering an expansion tube. The nucleation ring may also be placed at the beginning of a nozzle such that cavitation starts within the nozzle.

  • Publication number: 20110030390
    Abstract: A vortex tube allowing for control of the velocities, flow, and pressure differentials otherwise present in a free vortex like that found in a tornado is disclosed. The presently disclosed vortex tube may be used for the control and implementation of the otherwise chaotic aspects of a true tornado and vortex (i.e., with less energy and a narrowed and more focused and intense vortex) when implementing the critical flow regime in a fluid flow system.

  • Patent number: 5676536
    Abstract: Raw gas burner that maximizes fuel efficiency of the burner, minimizes residence time, and reduces or eliminates flame contact with the process air or gas in order to minimize NOx formation. Process air flow such as from the cold side of a heat exchanger associated with thermal oxidizer apparatus is directed into and around the burner. The amount of process air flowing into the burner is regulated based upon the pressure drop created by the burner assembly. The pressure drop is, in turn, regulated by one or more of an external damper assembly, an internal damper assembly, and movement of the burner relative to the apparatus in which it is mounted. To ensure thorough mixing of the fuel and process air, process air entering the burner is caused to spin by the use of a swirl generator. The fuel/process air mixture proceeds into the combustion section of the burner, where the swirling flow is caused to recirculate to ensure complete combustion of the fuel in the combustion chamber.

  • Patent number: 5618173
    Abstract: Process and apparatus for burning combustible constituents in process gas in a main combustion enclosure, preferably a thermal post-combustion device, whereby the main combustion enclosure is separated from a combustion chamber, into which oxygenic gas and gaseous fuel are fed, mixed and burnt. The fuel for the apparatus is fed through a lance which opens into a mixing chamber supplied with oxygenic gas, which is either itself the combustion chamber or merges with it, and the outer surface of the combustion chamber is exposed at least partially to the process gas. The fuel is burned completely or nearly completely in the burner combustion chamber and the mixture of burned fuel and gas leaving the combustion chamber oxidizes the combustible constitutes in the process gas flowing outside of the combustion chamber by yielding flameless heat energy to them.
