• 中文摘要： 本文藉因次分析，利用斷面積分法將控制流場的連續方程式、運動方程式、浮昇方程式及射流軌跡方程式求解，以探討具均勻橫向流動密度層變流中，垂直入射浮昇射流之發展特性。並配合水槽的實驗以檢定數學模式的運算結果。比較顯示結果相當良好。
• 英文摘要： In this study, by combining dimensional analysis with the integral approach, which consists of inte-grating the equations of continuity, motion and density deficit across the jet cross section, we investigatethe time average behavior of a vertical round buoyant jet in a uniform horizontal cross flow of stably stra-tified density. The model predicts the vertical rise and the dilution of the jet as a function of horizontalposition. A comprehensive experimental program performed in a flume was also conducted to enable veri-fication of the calculating relationships. Results show that the comparisons between the numerical calcula-tion and the laboratory experiments are favorable.
