Abstract: Flow blurring injection utilizes a two-phase concept to generate fine sprays immediately at the interior exit, rather than a typical jet which gradually disintegrates into ligaments and then finer droplets for a conventional injector. Therefore, clean combustion is achieved with the FB injection for fuels with distinct properties without fuel preheating or hardware modification. However, in addition to the droplets, the FB injection also produces ligaments for highly viscous liquids and relatively larger droplets at spray edge, resulting in difficulty in sustaining the flame and performs incomplete combustion and higher emissions close to the combustor all. The disclosed swirl burst injector and method utilizes the advantages of FB injection and swirl atomization to further improve atomization, and overcomes the limitations of FB injection, providing a sustainable way to use both conventional and alternative fuels with improved efficiency and minimized emissions. The fine atomization of the present invention can be also used in various applications where fine sprays are needed.

Abstract: Thermal spray processing and cold spray processing are utilized to manufacture porous starting materials (such as tube stock, wire and substrate sheets) from biocompatible metals, metal alloys, ceramics and polymers that may be further processed into porous medical devices, such as stents. The spray processes are also used to form porous coatings on consolidated biocompatible medical devices. The porous substrates and coatings may be used as a reservoir to hold a drug or therapeutic agent for elution in the body. The spray-formed porous substrates and coatings may be functionally graded to allow direct control of drug elution without an additional polymer topcoat. The spray processes are also used to apply the drug or agent to the porous substrate or coating when drug or agent is robust enough to withstand the temperatures and velocities of the spray process with minimal degradation.

Abstract: The powder injection system consists of a dosage chamber directly fed by a conventional powder feeder and communicated with barrel of the detonation gun through a direct conduit. In this way, the pressure wave advancing through barrel enters the communication conduit and upon reaching dosage chamber undergoes a sudden expansion, interrupting powder feeding from the continuous feeder and causing the full fluidization of powder contained in dosage chamber. The fluidized powder is suctioned to barrel where it remains until the pressure wave generated in a new detonation cycle carries it away, depositing it on the surface of the part to be coated.

Abstract: A detonation coating apparatus that coats a substrate with a coating powder which is propelled by the products of a detonation. The present invention increases the rate at which the coating is applied by increasing the detonation rate of the combustible gas mixture. The detonation coating apparatus is a self-detonating apparatus designed to create a secondary pressure within a combustion chamber. This secondary pressure combines with an initiating element, which is heated by detonation to a temperature, to ignite the combustible gas mixture as rapidly as the secondary pressure originates.

Abstract: An energy bleed apparatus and method for a detonation gun apparatus utilizing bleed apertures to remove reflected energy from interfering with the detonation wave front. The energy bleed system is positioned in the downstream portion of the combustion chamber of the detonation gun. The bleed apertures extract energy from the combustion chamber that would otherwise be reflected off the combustion chamber walls and collide with the detonation wave front, thereby permitting a maximum amount of energy to be transferred directly to the coating powder being applied. The increase in energy translates into better quality coatings and an associated increase in productivity of the overall coating process.

Abstract: A gas detonation sprayer includes a barrel with a three-part combustion chamber and a gas distributor which is fluidly coupled to the first part of the combustion chamber. The gas distributor includes passages through which fuel gas and oxygen pass and are mixed. The first part of the combustion chamber is annular and includes a spark plug. The second part is cylindrical and has a plurality of peripheral channels which fluidly communicate with the first part. The third part is cylindrical and is fluidly coupled to the second part, and to the proximal end of the main barrel. The combustion chamber and the main barrel are housed in a casing which includes water cooling passages. A powder feeding tube passes axially through the first and second parts of the combustion chamber and terminates inside the third part. A first embodiment of the gas distributor includes two narrow annular passageways which are fluidly coupled to each other by an axial opening and to an axial outlet. Fuel gas is mixed in one of the annular passageway and oxygen is injected into the other passageway. Mixed fuel gas and oxygen exits through the axial outlet to the first part of the combustion chamber. A second embodiment of the gas distributor has separate narrow diameter passages for fuel gas and oxygen. The dimensions of the passages are chosen according to a hydrodynamic Peclet criterion so that detonation wave damping is effected to prevent backfire.

Abstract: A repetitive combustion coating apparatus for applying coatings of particulate materials such as powdered tungsten carbide and other metal alloys by discharging discrete quantities of material encapsulated in an elongated tape into a combustion chamber and igniting a fuel-air mixture therein to deliver the charge of combustion gases and entrained particulate material through a nozzle to impact the article to be coated. The apparatus includes a rotary indexing wheel over which the encapsulated tape is trained with the spaced apart capsules nested in circumferentially spaced supporting receptacles. The indexing wheel is mounted on support arms which permit limited linear reciprocation so that a ratchet mechanism incrementally indexes the wheel and permits linear movement of the wheel to successively clamp the tape capsules against a clamping die. High pressure gas is introduced through a support spindle for the indexing wheel and internal passages in the wheel to burst a capsule and deliver a charge of particulate material into a combustion chamber. The indexing of the wheel is controlled by a detent mechanism to compensate for dimensional variations in the various structural parts of the apparatus. A control system provides a timed sequence of events to deliver a charge of fuel-air mixture to the combustion chamber as well as a charge of particulate material and ignition of the mixture.

Abstract: The invention relates to the application of powder coatings to vital components of equipment in various industries. The apparatus comprises a barrel for application of powder to the article and a gas distribution unit which connects fuel gas feeding passages and a purging gas feeding passage to the barrel. Gases are fed to outlet pipes of gas passages from appropriate gas sources under pressure through valves mounted in the pipes. The outlet opening of the purging gas passage may, in some embodiments, be located upstream of the zone of admission of fuel gases to the barrel in the path of flow of purging gas. The pressure of the purging gas source exceeds the pressure of each of the fuel gas sources so that, upon feeding fuel gas to the barrel, the valves mounted at the outlet pipes of the fuel gas passages shut-off these pipes. After the valve mounted in the purging gas passage is closed, the valves mounted in the fuel pipes admit fuel gases to the barrel to build-up a detonation wave.
