摘要
对二维对称文丘里通道内流动进行了数值模拟,研究了其流场分布随雷诺数的变化规律,探讨了对称结构下出现的非对称流动与文丘里管尺寸结构的关系,以及产生非对称流动的原因,分析了文丘里管流动问题中的非线性特性。
The flow in the two-dimensional venturi channel was studied by numerical simulation,and the variation rules of the flow field distribution changing with the Reynolds number were given. The asymmetric flow phenomena under the symmetric structure,and its relationship with venturi structure size were discussed. Then the causes of asymmetric flow and the nonlinear characteristics of venturi flow problem were analyzed.
