Filed:

Dec 23, 2020

Appl. No.:

17/131905

Inventors:

- Johnston RI, US
Gregory M. Laskowski - Waltham MA, US

International Classification:

G16H 50/50
G06F 30/25

Abstract:

Described are computer aided techniques to simulate a human respiratory event. The computer aided techniques access a model including a portion of a person's respiratory tract, which models the respiratory tract as a volumetric region, initiate a respiratory event into the volumetric regions, which respiratory event originates in the accessed model at a depth that is inside of the modeled respiratory tract, simulate movement of elements of the respiratory event within the volumetric region, with the elements representing particles of the respiratory event, at an inlet boundary condition representing an area of the model that is at the threshold depth inside the respiratory tract, and obtain from the simulation, a representation of a trajectory of particles of the respiratory event.

Abstract:

A turbine engine having an inducer assembly. The inducer assembly includes a centrifugal separator fluidly coupled to an inducer with an inducer inlet and an inducer outlet. The centrifugal separator includes a body, an angular velocity increaser to form a concentrated-particle stream and a reduced-particle stream, a flow splitter, and an exit conduit fluidly coupled to the body to receive the reduced-particle stream and define a separator outlet.

Abstract:

A turbine engine having a bypass fluid conduit coupled to the turbine section includes at least one particle separator located within the bypass fluid conduit to separate particles from a bypass fluid stream prior to the bypass stream reaching the turbine section for cooling. A centrifugal separator for removing particles from a fluid stream includes an angular velocity increaser, a particle outlet, an angular velocity decreaser downstream of the angular velocity increaser, and a bend provided between the angular velocity increaser and the angular velocity decreaser.

Abstract:

A shroud assembly for a gas turbine engine includes a shroud, hanger, and a hanger support mounted adjacent to a plurality of blades. The hanger can have an interior chamber defining a cooling circuit with a particle separator located within the interior chamber. The particle separator can have an inlet for accepting a flow of cooling fluid, such that a the flow of cooling fluid separates into a major flow and a minor flow carrying particles or particulate matter along the minor flow into a particle collector comprising at least a portion of the particle separator. Particles become constrained to the minor flow and pass into the particle collector, while the major flow is separated into the remaining area of the interior chamber to remove the particles from the flow of cooling fluid passing into the interior chamber.
