摘    要:提出挠流阻力引起探针杆挠曲造成水流场测量误差的迭代计算修正方法。分析该方法的收敛性及收敛方式。结果表明:通常情况下该方法是收敛的。计算流速矢量具有从两侧交替和右侧逼近实际流速矢量两种收敛方式,该方法可用于探针杆挠曲引起的流速场测量误差的修正计算。

关 键 词:五孔探针  流场测量  针杆挠曲  误差修正  收敛性

Abstract:A method was proposed to correct errors in water flow field measurements with 5 hole probe because of rod bending caused by flow drag. The convergence of the computing method was analyzed. The results indicate that the method is generally, convergent and for the computation of velocity vectors there are types of convergence: from two sides alternatively and from the right side to approach real velocity vectors. The method was proved to be effective in error correction errors.
Keywords:five  hole probes  flow measurement  bending of probe rods  correction  convegence
