Wall effect of the non intrusive ultrasound Doppler velocimetry ( UDV ) measurements was investigated experimentally to modify the measurement error due to the wall effect in the Doppler angle and measurement location by a commercial ultrasound Doppler velocimetry .
为了校正商用超声Doppler测速仪由于没有考虑壁效应而在Doppler角度和测量位置的确定上引起的较大误差，对超声Doppler测速仪（UDV）在非接触式测量的壁效应进行了实验研究。
