An asymmetric inlet particle separator system (AIPS) includes a bifurcated duct system that defines an inlet for receiving inlet air. The bifurcated duct system includes a core air channel and a scavenge air channel and is configured to separate the inlet air into core air and scavenge air. The scavenge air channel includes a first plurality of turning vanes configured to turn the scavenge air in a first direction and a second plurality of turning vanes configured to turn the scavenge air in a second direction. The AIPS also includes an asymmetric scroll coupled to the scavenge air channel. The asymmetric scroll includes a first arm having a first arm length and a second arm having a second arm length that is different than the first arm length.

An air filter comprising a housing, a plurality of cyclonic-element arrays and a plurality of individual airflow paths is disclosed herein. The housing includes a first side configured to be arranged or otherwise exposed to an upstream side of a first airflow, and a second side configured to be arranged or otherwise exposed to a downstream side of the first airflow. In some embodiments, the plurality of cyclonic-element arrays may be organized in a parallel or approximately parallel arrangement within and/or supported by the housing. Further, the plurality of individual airflow paths may correspond to the plurality individual of cyclone elements in each array life.

A turbine engine having a compressor section, a combustor section, a turbine section, and a rotatable drive shaft that couples a portion of the turbine section and a portion of the compressor section. A bypass conduit couples the compressor section to the turbine section while bypassing at least the combustion section. At least one particle separator is located in the turbine engine having a separator inlet that receives a bypass stream, a separator outlet that receives a reduced-particle stream flows, and a particle outlet that receives a concentrated-particle stream comprising separated particles. A conduit, fluidly coupled to the particle outlet, extends through an interior of at least one stationary vane.

A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.

A cyclone filtering device includes first and second filters. The first filter includes a first filtering tube defining a first turbulence room, and has a coupling cover communicated with the first turbulence room and disposed for allowing passage of fluid, and a barrel seat defining a dust collecting room that is communicated with the first turbulence room. The second filter includes a second filtering tube defining a second turbulence room that is communicated with the first turbulence room, two end covers having an end opening that is communicated with the second turbulence room, and a capture member disposed in the second turbulence room and disposed for capturing substances that are entrained in the fluid.

A bioluminescent tornado maker system for creating a pleasing, glow-in-the-dark tornado. The bioluminescent tornado maker system generally includes a base that supports a transparent vessel having a liquid within it. The liquid may be salt water, and may contain bioluminescent organisms, such as dinoflagellates. An impeller in the base in contact with the liquid causes a rotational flow of the liquid, creating a visible vortex and also a mechanical disturbance that causes the bioluminescent organisms to emit a visible light, resulting in a glow-in-the-dark tornado.

Dust separation devices are disclosed to enable separating and collecting dust particles. A parabolic cyclone chamber is disclosed. The parabolic cyclone chamber has a bottom having an opening, an upper surface, a curved sidewall connecting the bottom to the upper surface, an entry path in a top portion of the cyclone chamber, an exit path extending through the upper surface, and a diverter wall sloping downward from the upper surface of the cyclone chamber toward the entry path.

A demister apparatus for machine tools having an enclosure booth for confining mist in which a varying outflow of air is drawn from the booth and directed to a remote demister apparatus from a minimum when the access doors to the enclosure are closed to a maximum when one or more of the doors are opened. The air flow may also be varied with the number of machine tools in operation as well with the state of filters in the remote demister apparatus. A cyclonic separator is also provided adjacent to the booth which functions well in a vertical up flow mode over a range of air outflow rates of flow.
