中文摘要 | 本文之重點集中在一受侷限橫向流場中噴流之衝壁過程,以及對衝噴流互撞之行 為。基本言之,側向噴流結構為一對反轉渦流所掌控,而在高噴流動量之情況下,渦流與邊 壁的交互作用及側向噴流迎面對撞之過程卻大異其趣,流場型態之發展迥異。本文工作首先 進行相關之文獻調查,然後再以流場具像化方式顯現其流場結構。其主要目的是研究側向噴 流在不同邊界條件下衝擊過程之差異性,以蒐集此類流場型態在實際應用上相關的設計基準 資料。 |
英文摘要 | This paper is focused on the impingement processes of a single jet to the opposite wall or between opposite jets in a confined cross flow. Basically, the structure of a transverse jet is dominated by a pair of counter-rotating vortices; however, for jets with high momenta, the interactions among the vortices and the confined wall are quite different from the counterparts between opposite jets, and the subsequent flow pattern developments are different as well. A comprehensive literature survey is conducted first in this work, then the flow structures are elucidated by flow visualization techniques. The primary goal of this study is to investigate the difference of impingement processes of transverse jets under various boundary conditions, for acquiring related design bases for this kind of flow pattern in practical applications. |
