In the development of numerical codes for the prediction ofaerodynamic flows is a strong need to obtain reliable flow field datawhich is suited to validate turbulence models used in numericalcalculations. In three dimensional boundary layers Laser-DopplerVelocimetry (LDV) is the appropriate technique usually applied to obtainthis kind of data. Since LDV, being a single point measurementtechnique, is a time consuming method, it is desirable to have theability to make use of data from different experiments and researchgroups. Therefore it is necessary to have a standard to compareexperimental results obtained by different LDV processors and to definea consistent mathematical algorithm to process data from the differentLDV experiments. This is the objective of the present paper. In anEuropean activity four different research groups have conducted commonexperiments in industrial wind tunnels and finally compared the resultsto qualify LDV for the application in industrial wind tunnel and todefine a standard to compare LDV data coming from differentsources
