摘要(Abstract):

应用计算流体力学软件Fluent对9-26型高压离心风机内部的三维气体流动进行了数值模拟与分析。计算中采用了标准k-ε湍流模型与非结构化网格。同时对计算结果进行了分析。模拟结果有助于理解风机内部的流动规律。
Computation fluid dynamics Fluent is applied and the three dimensional air flows in the blower are numerically simulated and analyzed.Standard k-ε turbulent model and unstructured grid are applied in computation and the calculating results are discussed.The calculating results are very helpful for people to understand flow pattern in the blower.
