摘要： System and method for automatically determining a final set of tuning/calibration parameters for designing a new turbo-machinery. The method includes inputing an initial set of tuning/calibration parameters; calculating family turbo-machinery quantities based on the initial set of tuning/calibration parameters; comparing the calculated family turbo-machinery quantities with measured quantities and calculating a first error between the calculated family quantities and the measured quantities; calculating a second error between the initial set of tuning/calibration parameters and default values of the turbo-machine variables; forming a modified objective function that includes both the first and second errors; during an iterative process, varying the initial set of tuning/calibration parameters in such a way that the final set of tuning/calibration parameters is found; and storing in a database the final set of tuning/calibration parameters for the family.

摘要： A machine having a fixed part including a portion with a smooth surface is provided. The machine also includes a rotating part configured to rotate relative to the fixed part, the rotating part directly facing the portion of the fixed part, and plural ridges formed on the portion of the fixed part directly facing the rotating part, the plural ridges comprising an abradable material, wherein the abradable material is configured to be inoperable at temperatures above about 1000° C.
