An Automatic Velocity Measurement using Image Processing Technique and its Particle Tracking

2nd Report An automatic estimation method of the detectiog area for the particle tracking

Abstract

A new technique for the particle tracking of two dimensional turbulent flow was developed using the image processing technique, The motions of fine particles are extracted automatically by the tracking algorithm in which the correlation method for the estimation of the detecting area of the particle tracking is included.
This algorithm is applied to the flow field behind a turbulence promoter and the applicability to turbulent wake flow is examined.
