自然対流場における速度場の三次元画像計測

抄録

This paper describes quantitative 3-D measurement method for flow field of a rotating Rayleigh-Benard convection in a cylindrical cell heated below and cooled above. A correlation method for 2-D measurement is well advanced to a spatio-temporal correlation method. Erroneous vectors, often appeared in the correlation method, is successfully removed using Hopfield network. As a result, calculated 3-D velocity vector distribution well corresponds to the temperature distribution.
