ABSTRACT:
A turbine airfoil is disclosed. The airfoil includes one of a turbine shroud, liner, vane or blade, including an airfoil sidewall having a film-cooling hole that extends between an airfoil cooling circuit and an airfoil surface. The airfoil also includes an insert disposed in the film-cooling channel having a body. The body has a proximal end configured for disposition proximate the airfoil surface and a distal end. The body is also configured to define a passageway that extends between the distal end and proximal end upon disposition in the film-cooling hole.
