本文以風洞實驗方法探討在均勻紊流場中，流經二維矩形柱之渦散現象受逼近流場之紊流強度，紊流長度尺度，以及模型斷面長寬比等參數之影響。本實驗是以兩根熱膜探針置於柱體背後的順風向（Ｘ），橫風向（Ｙ），及軸向（Ｚ）的佈點上量測其尾流速度場。從量測點，求得平均速度，擾動速度之均方值，頻譜，時間相關函數和頻率相關函數，以探討在上述的控制參數下對尾流渦散的影響。This paper is an experimental investigation of the development of the vortex shedding behind a 2-D rectangular cylinder in homogeneous turbulent flows with different variation of turbulence intensity, turbulence length scale, and cross-section of the cylinder. measurements of the velocity in the wake of the cylinder were performed at points in alongwind direction (X), acrosswind direction (Y), and spanwise direction (Z) behind the rectangular cylinder using two hot film probes. The data were analyzed for the calculation of the mean velocity, r.m.s. velocity fluctuation, time cross-correlation, spectrum, and coherence. The results were used to evaluate the effects of the above parameters on the development of the vortex shedding.
