Paper Abstract

An application of speckle velocimetry technique to Rayleigh-Benard convection (small boxes) is presented. A 5 mW He-Ne laser allows precise determination of the 2-D velocity flow field, up to several mm/sec. The digital techniques used to analyze automatically the multiexposed photographs and to generate velocity and vorticity fields are described. The obtained results are in good agreement with previously reported data. The ability of the technique to cover other experimental conditions is discussed.
