Abstract
A shrouded turbine airfoil () with a leakage flow conditioner () configured to direct leakage flow to be aligned with main hot gas flow is disclosed. The leakage flow conditioner () may be positioned on a radially outer surface () of an outer shroud base () of the outer shroud () on a tip () of an airfoil (). The leakage flow conditioner () may include a radially outer surface () that is positioned further radially inward than the radially outer surface () of the outer shroud base () creating a radially outward extending wall surface () that serves to redirect leakage flow. In at least one embodiment, the radially outward extending wall surface () may be aligned with a pressure side () of the shrouded turbine airfoil () to increase the efficiency of a turbine engine by redirecting leakage flow to be aligned with main hot gas flow to reduce aerodynamic loss upon re-introduction to the main gas flow.
