| Summary: | 碩士 === 國立中正大學 === 物理學系暨研究所 === 102 === This research was about the flow mixing of incompressible flow. The volume rate of flow in the closed pipe is related to the sectional area of the pipes and dynamic pressures. However, the volume rate of flow will change if the size of outlet changed. We found the nonlinear relationship between the volume rate of flow and the size of outlet. In experiment we try to prove that, the mixed pipes flow is not superposition of two single pipe flow.
Observation by the experiment as we know, after mixed the two different size of the inlet. The proportion of two inlet flow will biased one of them if the sectional area of the outlet has changed. That mean the downstream has changed that will influence the every tributaries of upstream.
With this study, will be able to predict the ratio of the upstream flow if we can understand the downstream change, and application in a variety of mixed-related systems.
