摘要
本文首次把S形翼型作为研究对象进行理论计算和试验研究。在理论方面,提出了一种计及粘性影响的S形翼型绕流流场的计算方法;在试验方面,利用水洞对S形翼型的绕流流场进行了实测。计算结果与试验结果吻合。
This paper deals theoretical and experimentally with the S-shaped airfoil for the first time. Theoretically, a method is developed of calculating the flow-field round the S-shaped airfoil with the effect of viscosity taken into consideration. Experimentally, the flow-field roud the S-shaped airfoil is tested by means of a water cave. Calculated results are found to be in agreement with measured ones.
