Apparatus for separating grit from a grit-loaded liquid matrix while retaining organic solids in suspension, including an inlet for admitting liquid matrix into the apparatus, an outlet for removing grit-lite liquid matrix from the apparatus main chamber, and a vortex system for removing separated liquid matrix grit from the apparatus. The grit settling main chamber defines upper and lower subchambers communicating with each other through a central aperture. A fluid flow speed gradient is established between the apparatus fluid inlet and outlet. An Eddy type fluid dynamic component is added, providing combined enhanced coarse grit and fine organics discrimination and separation. The Eddy fluid dynamic component may consist of a trio of stationary fresh water supply force fed eductors. Each eductor produces a fresh water fluid flow interacting with the liquid matrix fluid flow inside the upper subchamber, whereby Eddy-type turbulences are generating promoting fine, liquid matrix grit particle separation from the liquid matrix.

A method and apparatus for a turbine engine having a compressor section, combustion section, and a turbine section in an axial flow arrangement with a cooling circuit in fluid communication with at least one of the compressor section, combustion section, or turbine section. The method and apparatus further including separating particles from a cooling air that flows through the cooling circuit.

A vortex breaker for a particulate separator has a first set of vanes spaced along a perimeter of a first shape and a second set of vanes spaced along a perimeter of a second shape, where the second shape resides within the first shape. Each of the vanes has a top edge, a bottom edge, an inside edge, and an outside edge. The vanes in the first and second sets of vanes intersect the first and second shapes, respectively. The vanes in the first set are oriented in a first rotational direction, and the vanes in the second set are oriented in a second rotational direction that is opposite the first rotational direction. The first set of vanes and the second set of vanes define fluid flow paths between the outside edges and the inside edges of the sets of vanes.

A vacuum cleaner having a cyclone chamber comprising a cyclone air inlet, a cyclone air outlet, a cyclone axis of rotation, an axially extending cyclone chamber sidewall extending between first and second axially opposed ends. The cyclone chamber sidewall has a first sidewall portion that is axially moveably mounted with respect to a second sidewall portion of the cyclone chamber sidewall between a closed position in which the cyclone chamber is closed and an open position in which the cyclone chamber is opened.
