Turbine and method for separating particulates from a fluid

摘要

According to one aspect of the invention, a turbine airfoil (200) includes a first cavity (204) inside the turbine airfoil (200) configured to receive a fluid (208) and a second cavity (206) inside the turbine airfoil (200). The turbine airfoil (200) also includes a passage (210) inside the turbine airfoil (200) that provides fluid communication between the first and second cavities (204,206), wherein the passage (210) includes a curved portion (214) configured to separate particulates from the fluid (208) as the fluid flows through the passage (210).
