Abstract
A turbine bucket is provided and includes a shank defining a cavity therein, which is connectable with a rotor such that wheelspace air having an initial pressure is permitted to flow into the cavity and a platform coupled to the shank and defining a cooling hole therein, the shank and the platform each further defining the cavity and the cooling hole, respectively, as being fluidly communicative with one another, such that the wheelspace air permitted to flow into the cavity is deliverable from the cavity and through the cooling hole at a second pressure greater than the initial pressure.
