本實驗使用視流技術之彩色紋影法與動態壓力測量技巧來探討及比較在有無電漿所產生的離子風在楔形體35度與50度斜面模型上與平面震波交互作用下，其反射震波的結構差異。由於模型角度的差異，在馬赫數為1.35到1.64之間，震波分別在50度模型產生正規反射及35度模型上產生馬赫反射。本研究亦分析了隨著馬赫數的增加，入射震波與反射震波之間的夾角變化與震波強度的變化。由實驗結果的彩色紋影法圖可得知入射震波與反射震波的夾角於無離子風時，隨著入射震波的增強而角度變大，相對之下在有離子風效應下此夾角的變化不明顯。由動態壓力量測結果顯示，在比較有/無電漿產生的離子風效應下的反射壓力脈波，無明顯減弱的趨勢。與前人所使用電漿產生的電暈效應結果相互比較之下，電漿所產生的電暈效應使得震波結構衰減較為顯著，因此發現電暈效應較離子風效應為佳。

The study on a thirty-five degree wedged model and fifty degree wedged model with and without low temperature plasma induced ionic wind under the interaction of a planar shock wave have been done by the color Schlieren flow visualization technique and the dynamic pressure measurement method. It has been shown that with the incident shock Mach number of the range 1.35 to 1.64 there are Mach reflection and regular reflection for wedged models of 35° and 50° respectively. The color Schlieren photographs show that that the angle between incident shock and reflected shock become larger as Mach number increased. These angles do not change much under the influence of the ionic wind. The measured dynamic pressure of reflection shock wave also indicates that its strength is unchanged for models with lower incident Mach number under the influence of ionic wind. Compare with the experimental results with influence of low temperature corona，it has been shown that the reflection shock wave becomes weaker as the incident shock wave pass through the corona. Hence, it is concluded that the corona effect is more efficient than the ionic wind.
