摘　　要：本文采用时间相关有限体积法编制了计算透平级中跨音速全三元流场的程序,并对引进的300MW汽轮机末级流场作了初步的计算。认为:随着计算机和计算技术的发展,采用全三元流场的计算方法将是今后计算、设计透平的发展方向。A program for turbine transonic three dimentional flow field calculation has been worked out by the time marching method, with which the preliminary evaluation of the licensed 300MW turbine's last stage has been performed. The paper stresses that, with the development of computers and computation techniques, future turbine design is featured by three dimensional flow field calculation.
