| Abstract: | Finger seal is a new kind of sealing technology th at can be used in gas turbines with competitive properties. Study on this techno logy is helpful for improving the performance of gas turbine. As an example, the structural optimization model of finger seal with involute shape-curve is pres ented, whose objective function is low hysteresis of finger seal. Based on the A NSYS software package, the structural optimization of finger seal is carried out and a set of optimum parameters is obtained, which offers a useful method and r esult for further study on finger seal. |
