| 9. | The results indicate that the recirculations are caused at the closed end of the main duct and near the lower wall of the main duct in the lower side duct , and the secondary recirculation in the main duct ' s cross section , which appears only near the lower side duct , is caused due to section enlargement as gas enters the main duct from the side duct , when gas enters only at the entrance of the side duct
实验结果表明，在只有支管进气的情况下，在总管的封闭端和支管下游总管壁面处产生了回流；以及气流从支管进入总管后由于截面扩张在总管横截面上所诱发的二次流，并且二次流现象只发生在支管下游附近的总管横截面上。 |
