| 摘 要： | 采用商用软件FLUENT对双三次曲线和维辛斯基曲线这两种收缩段曲线进行了数值模拟,旨在通过仿真结果为低速风洞收缩段的设计选择一种较为合适的曲线。从流函数、静压、速度图中可以看见,收缩段曲线采用双三次曲线时各截面参数均匀,可以达到很好的收敛效果,通过本次数值模拟计算可为低速直流风洞的设计及优化提供了重要的依据。

| Abstract: | The numerical simulation of two types of contra-ction curve double cubic curve and Vyshinsky curve, are made using the FLUENT software. Through the result of numerical simulation, an appropriate curve is selected for the design of low speed wind tunnel contraction section. From the flow function chart, static pressure chart and velocity chart, we find that the cross section parameter of doule cubic contraction curve is uniform and can gain good contraction effect. The numerical simulation benefits the design and optimization of the low speed blow down wind tunnel. |
