A high pressure turbine (HPT) blade includes a substantially arcuate trailing edge including one or more fluid injection elements disposed therein. Each fluid injection element injects a fluid such as air into a desired trailing edge region of the HPT blade or vane to enhance mixing out of the wakes generated via the HPT blade or vane. The enhanced mixing out reduces HPT/LPT interaction losses and/or the axial gap between the HPT and LPT components in a gas turbine engine. The interaction losses include unsteady thermal wake segregation effects that lead to unexpected heat-up of endwalls (planforms and blade/vane-tips) of downstream blades/vanes, and further include aerodynamic losses, both transonic and subsonic.
