该文采用双时间步法,较为方便地将孤立叶排定常流场求解拓广为转/静干扰非定常流场时间精确求解,而且该流场时间精确求解方法收敛速度较作者最初工作有较大提高.文章通过对一跨音风扇级非定常流场时间精确模拟,对叶轮机非定常流动建立了一定理解.“,”By utilizing “Dual Time Step” technique, an isolated blade row flow-field solver is readily extended to simulate Rotor/Stator interaction phenomena. With Time-Accurate simulation about one transonic fan stage unsteady flow, some sketches related to unsteady flow are understood. Although very valuable results have been obtained t Time-Accurate solutions still give us little conclusion that may be served as criteria for turbomachinery design. As a result, Investigations about Rotor/Stator interaction must be continued before Time-Accurate design can step into realities.
