Measurements of the three-dimensional flow velocity components (u, v, w) are carried out around a 2 m Inuid Model M 21 where a specially developed mini five-hole pitot tube of 6 mm diameter is applied satisfactorily.<BR>The velocity components are analyzed (u, v, w-analysis) in a synthetic co-ordination with the corresponding wave analysis (C-analysis) which was previously reported on the same model (M21).<BR>The study indicates that, i. e.<BR>For potential field ;<BR>(1) The two linearized free surface conditions, i. e. the “atmospheric” condition as well as the “kinematical” condition, are both valid either between ζ (measured) and u (measured) or between ∂ζ/∂χ (measured) and w (measured).<BR>(2) The behaviour of the transverse componentv (y) is the most important, because this, component alone can give the unique informations for sheltering effects which are not included in the wave-analysis.<BR>(3) The results analyzed from u or w are almost similar to those already obtained by wave analysis.<BR>For viscous field ;<BR>(4) The flow field analysis is useful also for the refinement of the wake-survey by enabling the quantitative estimation of the disturbance velocity (u1) which is fictitiously presumed within the wake belt.
