Abstract Wall shear stress and wall streamline direction measurements were conducted on a generic delta wing model to demonstrate the potential of the white-light oil-film interferometry in three-dimensional flows. With the proposed algorithm, an automatic oil-film thickness calculation is possible and yields reproducible and plausible wall shear stress distributions on the leeward side of the delta wing for various angles of attack.

通过白光油膜干涉法测量壁面剪切应力

摘要 在通用三角翼模型上进行壁面剪应力和壁面流线方向测量，以证明白光油膜干涉测量法在三维流动中的潜力。使用所提出的算法，自动油膜厚度计算是可能的，并在三角翼背风侧针对各种攻角产生可重复且合理的壁面剪应力分布。图形摘要
