ABSTRACT:
A system for cooling includes a surface to be cooled, at least one film-cooling hole within the surface for allowing a film cooling jet of coolant to reach the surface, each of the at least one film-cooling hole having a diameter and at least two spaced apart flow-aligned blockers positioned downstream of the at least one-film cooling hole, each of the flow-aligned blockers extending upwardly from the surface to assist in preventing hot-gas entrainment and increasing adiabatic effectiveness by confining coolant flow downstream of the at least one film-cooling hole between the blockers.
