Abstract
A layout for asymmetric trip strips including a flow passage having a lower wall and an upper wall opposite the lower wall, each of the lower wall and the upper wall including an inner surface, the flow passage having a passage inlet and a length L and a diameter d; multiple skewed trip strips extending from at least one inner surface of the lower wall or the upper wall; and at least one periodic reflection of the skewed trip strips along the flow passage downstream of the passage inlet at a frequency with a length-to-diameter ratio of L/d≤20.

A layout for asymmetric trip strips comprising:
- a flow passage having a lower wall and an upper wall opposite the lower wall, each of the lower wall and the upper wall including an inner surface, the flow passage having a passage inlet and a length L and a diameter d;
- multiple skewed trip strips extending from at least one inner surface of the lower wall or the upper wall;
- and
- at least one periodic reflection of the skewed trip strips along the flow passage downstream of the passage inlet occurs at a frequency of L/d≤20.
A layout for asymmetric trip strips for a component for a gas turbine engine comprising:
- an external surface bounding a gas path of the gas turbine engine;
- a flow passage having an inlet configured to deliver an airflow therethrough, including:
- an internal surface located opposite the external surface, the internal surface and the external surface together defining a component wall;
- a plurality of skewed trip strips located along the internal surface, each skewed trip strip extending from the internal surface;
- and
- at least one periodic reflection of the skewed trip strips along the flow passage downstream of the passage inlet occurs at a frequency of L/d≤20.
A process for managing a fluid flow through a flow passage having asymmetric trip strips for a gas turbine engine component comprising:
- bounding a gas path of the gas turbine engine with an external surface;
- delivering an airflow through a flow passage having an inlet;
- defining a component wall with an internal surface located opposite the external surface;
- locating a plurality of the asymmetric trip strips along the internal surface, each asymmetric trip strip extending from the internal surface;
- and
- locating at least one periodic reflection of the asymmetric trip strips along the flow passage downstream of the passage inlet occurring at a frequency of L/d≤20.
