摘　　要：用FLUENT软件模拟计算扩散弯道内部流动,阐述了数值计算的求解过程和方法。计算对比了无导叶、有导叶扩散弯道的运行效率。为使用CFD求解计算流动问题提供了有益的参考,并为扩散弯道的运行效率的研究提供了数值实验依据。The paper introduces the numerical simulation of the flow inside the curved diffusers with the software of FLUENT, explains the solving process and methods of the numerical simulation, and calculates and compares the operational efficiency of vane and vaneless curved diffusers. This provides a favorable reference for solving the flow problems with CFD solution, and a numerical experimental basis for the research on operational efficiency of the curved diffuser.
