Abstract
In order to increase the velocity measurement precision of hydroxyl tagging velocimetry(HTV),experimental data were fitted with Gaussian function because the intensity of the tagging lines is in Gaussian distribution along width direction.Then the fitted peak position was regarded as the center position of the tagging lines.Finally with the center position as reference position,typical measurement data for hydorxyl tagging velocity were processed.The results show that the precision of velocity can be improved distinctly by means of this algorithm.
