Method for arranging of impingement cooling holes and effusion holes in a combustion chamber wall of a gas turbine

摘要

The method involves selecting a pattern of each of effusion holes (32), and determining a diameter of each effusion hole when selection of another diameter of each effusion hole is not successful, and quality specifications are not satisfied. Input data of a sum of geometrical areas of the effusion holes, a sum of geometrical areas of impingement cooling holes (31), and a surface to be cooled is checked when the selection of the pattern of each effusion hole is not successful. The quality specifications are changed when checking of the input data is not successful. An independent claim is also included for a combustion chamber wall.
