Abstract
An airfoil for turbomachines includes a first plurality of projections coupled to a suction sidewall adjacent a trailing edge and extending from the suction sidewall towards a pressure sidewall. A second plurality of projections is coupled to the pressure sidewall adjacent the trailing edge and extending from the pressure sidewall towards the suction sidewall. The airfoil includes a divider coupled to the first and second pluralities of projections and extending within a space between the first and second pluralities of projections. A first cooling channel is defined adjacent the suction sidewall and a second cooling channel is defined adjacent the pressure sidewall. The first and second cooling channels are configured to receive a coolant stream. The first plurality of projections is configured to meter the coolant stream through the first cooling channel and the second plurality of projections is configured to meter the coolant stream through the second cooling channel.
