An experimental study on a static pressure measurement errors in wall taps was conducted using a high Reynolds number actual flow facility (Hi-Reff). The bulk Reynolds number Re_D examined was up to 1.3 × 10⁷ and tap Reynolds number Re_t was up to 8.5 × 10⁴. The behavior of the static pressure measurement error at high Reynolds numbers was clarified experimentally. The static pressure measurement error normalized by wall shear stress increases with Reynolds number and reaches an asymptotic value. Its maximum value is 7.1 at Re_t = 8470. The asymptotic value increases with the size of the tap diameter up to 6 mm and then becomes constant for tap diameters exceeding 6 mm. The universal curve reported in previous studies is observed for only a limited range of tap Reynolds numbers of below 700 and of tap diameters below 4 mm.

使用高雷诺数实际流量设备（Hi-Reff）对壁式水龙头中的静压测量误差进行了实验研究。检查的总雷诺数Re _D高达1.3×10 ^7，而分接雷诺数Re _t高达8.5×10 ⁴。通过实验阐明了高雷诺数下静压测量误差的行为。通过壁切应力归一化的静压测量误差随雷诺数增加而达到渐近值。在Re _t时最大值为7.1 =8470。渐近值随丝锥直径的增加而增大，直到6 mm，然后对于超过6 mm的丝锥直径变得恒定。仅在有限范围内的小于700的抽头雷诺数和小于4 mm的抽头直径上观察到了先前研究中报道的通用曲线。
