This paper is a condensed description of a study of wind tunnel model simulations of dense gas clouds released instantaneously in the atmosphere, undertaken to assess the validity of the wind tunnel modelling technique as a dispersion prediction method [1]. The comparative data used was that obtained from the field trials carried out at Porton Down in 1976/7. In addition a number of scaling experiments were carried out in order to further investigate the modelling technique.
