- 中文摘要: 本文以實驗的方法,探討密度層變流中浮昇射流上昇的高度與特性。利用鹽水?加的方法,在實驗水槽中?製層變的環 境水域,並引用流場拍攝的技巧以查?及記錄流場的流況發展與變化。經由因次分析,獲得浮昇射流的上昇高度和射流排除條件與環境水域層變的函數關係。實驗的結果得到,在S>1的層變水域中,浮昇射流的上昇高度正比於F02/3 及 S1/2。
- 英文摘要: The maximum height of rise of plane turbulent buoyant jets discharged vertically into stratified ambient fluid is studied experimentally. By using the dimensional analysis, the ceiling height of rise of jet is related functionally to the discharge configurations and stratification of environments. In the laboratory experiments, a filling salt solution process is designed to generate a linearly density-stratified environment and a photographic technique is used to trace the development of the flow. It is found that the maximum height of rise of a plane vertical jet is proportional to F02/3 and S1/2 in density-stratified environments of S>1.
