摘　　要：波转子可以在不提高涡轮前温度的条件下提高燃气轮机循环的最高温度以及增压比,进而改善燃气轮机性能.本文提出了一种解析的波转子初步设计方法,在其中引入流量平衡约束条件,并用数值模拟验证了该方法的设计精度.该方法求解得到波转子的参数化设计空间,并由此归纳出波转子增压性能与压缩空气品质的优化设计方法.A wave rotor is an unsteady flow device enhancing a gas turbine with further compression and higher peak cycle temperature without raising the turbine inlet temperature. A new analytic method was established for wave rotor design. It integrated mass balance as an important design principle, and was validated by CFD. A comprehensive design space was generated with the analytic design method, and methods for optimization design were derived from it.
