| 摘 要： | １前言长期以来，深入揭示透平叶栅三维流场及其损失机理的研究一直是透平机械气体动力学研究的主要课题之一。由于叶栅流动极为复杂，影响因素多（有几何因素，如展弦比、气流折转角等；有气动因素，如来流流速、湍流度和附面层厚度等），人们对叶栅流动的复杂结构的认识...

| Abstract: | A 3D Navier-Stokes solver FINE/Turbo is used to numerically simulate the flow fieldsof a rotor cascade. Nearly 490 thousand grid points are used in this study in order tocapture detail flow structures. Comprehensive comparisons to the test results are made toverify the accuracy of the software. The results show that the software can be used to solvethe flow fields of straight cascade efficiently. Detail flow phenomena and three-dimensionalcharacteristics are revealed and its connections to total pressure losses are studied. |
