Turbine assembly and method for controlling a temperature of an assembly

摘要

According to one aspect of the invention, a turbine assembly includes a first component, a second component circumferentially adjacent to the first component, wherein the first and second components each have a surface proximate a hot gas path and a first side surface of the first component to abut a second side surface of the second component. The assembly also includes a first slot formed longitudinally in the first side surface, a second slot formed longitudinally in the second side surface, wherein the first and second slots are configured to receive a sealing member, and a first groove formed in a hot side surface of the first slot, the first groove extending axially from a leading edge to a trailing edge of the first component.

1. A turbine assembly comprising:
a first component; a second component circumferentially adjacent to the first component, wherein the first and second components each have a surface proximate a hot gas path; a first side surface of the first component to abut a second side surface of the second component; a first slot formed longitudinally in the first side surface; a second slot formed longitudinally in the second side surface, wherein the first and second slots are configured to receive a sealing member; a first groove formed in a hot side surface of the first slot, the first groove extending axially along the first component; and a second groove formed in a hot side surface of the second slot, the second groove extending axially along the second component; a lateral groove formed in the hot side surface of the first slot, the lateral groove extending from proximate an inner wall of the first slot, wherein the lateral groove routes a cooling fluid to the first groove, wherein the cooling fluid enters the first groove proximate a trailing edge side of the first groove and exits the first groove proximate a leading edge side of the first groove; an inlet passage extending circumferentially in the second component and configured to route cooling fluid to the second groove.
