| Summary: | 碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 96 === Fluid flow in the pipeline will be hampered by resistance. The resistance of fluid can be divided into primary resistance and secondary resistance. Primary resistance was due to fluid friction with pipeline. Secondary resistance was happened with fluid encountering turning point and the cross-section changed. In the past, artificer usually designed pipelines by his experience in traditional industries in Taiwan. He used feelings to handle the shape of pipeline. The situation of fluid in pipeline can not be completely known. In this paper, the CFD was be used to simulate the flow in pipeline and improve its efficiency.
The results of simulation show that changes in the geometry of the pipeline will lead to additional energy loss. Especially in the irregular shape of the components will result in the swirl. Different shapes of the entrance will not export the same velocity. The flow of segregation and collusion will make fluid mutual exclusion to influence the flow. To increase cross-sectional area can get better efficient than change the shape of hood. The smooth of flow may not be directly proportional to exhaust velocity. The minimum diameter department is mostly influence the efficiency of pipeline. Using the free space within plant to improve the efficiency of exhaust pipes is the best way.
