Abstract
An exhaust baffle apparatus includes an enclosure having longitudinal, lateral, and anterior dimensions. The apparatus defines an internal volume defining an airflow path proceeding from an intake opening to an exhaust opening. There are a multiplicity of mixers within the enclosure. Each mixer includes a length spanning the lateral dimension of the enclosure. Each mixer further comprises a hollow airfoil substantially open at lateral ends of the mixer and at least one vent oriented toward the exhaust opening. A different feature involves a method of dampening noise and heat form engine exhaust.
Claims27
An exhaust baffles apparatus, comprising:
- an enclosure having longitudinal, lateral, and anterior dimensions, the enclosure defining an internal volume defining an exhaust flow an airflow path proceeding from an intake opening to an exhaust opening;
- and
- a multiplicity of mixers within the enclosure, each mixer including a length spanning the lateral dimension of the enclosure transverse to the flow path, each mixer comprising a hollow duct substantially open at lateral ends of the mixer, each mixer having defined therein at least one vent oriented toward the exhaust opening;
- and
- wherein, at said lateral ends of the mixers, each said mixer is substantially open to an exterior of the enclosure.
A method of dampening noise and heat from engine exhaust, comprising operations of:
- directing engine exhaust into an intake opening of an enclosure defining an internal volume having opposing openings including the intake opening and an exhaust opening, and thereafter directing the engine exhaust along an exhaust path proceeding from the intake opening to the exhaust opening;
- and
- passing the directed exhaust across a multiplicity of mixers within the enclosure, each of the mixers including a length spanning the enclosure transverse to the exhaust path, each mixer comprising a hollow duct substantially open at lateral ends of the mixer and at least one vent oriented toward the exhaust opening;
- and
- wherein, at said lateral ends of the mixers, each said mixer is substantially open to an exterior of the enclosure.
An exhaust baffle apparatus, comprising:
- an enclosure having longitudinal, lateral, and anterior dimensions, the enclosure defining an exhaust flow path proceeding from an intake opening substantially near one longitudinal end of the chamber to an exhaust opening substantially near an opposing longitudinal end of the chamber;
- and
- a multiplicity of mixers within the enclosure, each mixer comprising a hollow duct spanning the enclosure transverse to the exhaust flow path, each said duct having distal ends substantially open to exterior of the enclosure, each said duct further including a vented region residing within the enclosure and being oriented substantially in a downstream direction of the exhaust flow path.
An exhaust baffle device, comprising:
- an enclosure having an inlet located substantially at one end of the enclosure and an outlet located substantially at an opposite end of the enclosure, the inlet and outlet defining therebetween an exhaust flow path having an exhaust flow direction;
- lying inside the enclosure perpendicular to the exhaust flow path, multiple substantially hollow ducts spanning the enclosure from side to side;
- where each duct includes longitudinal venting oriented toward a downstream direction of the exhaust flow path;
- and
- where each duct includes substantially open distal ends in fluid communication with an exterior of the enclosure.
A method for reducing exhaust noise from a gas turbine engine, comprising:
- providing an enclosure having an inlet positioned substantially at one end of the enclosure and an outlet positioned substantially at an opposite end of the enclosure;
- providing multiple substantially parallel and substantially hollow elongated mixers lying inside the enclosure and spanning the enclosure from side to side, each of the mixers being substantially open at lateral ends thereof to an exterior of the enclosure, each of the mixers further being vented in a longitudinal region oriented toward a predefined downstream direction of a predefined exhaust gas flow path;
- introducing a flow of exhaust gasses into the enclosure, the exhaust gasses traversing a route between the inlet and the outlet, said route forming the predefined exhaust gas flow path;
- and
- the exhaust gasses passing around and past the mixers while en route from the inlet to the outlet along the exhaust gas flow path.
