Résumé :
|
Kotsovinos (1976) shows that the apparently discrepant data for the jet spreading rate obtained by different investigators collapse rather accurately on a plot of jet width against downstream distance. The spreading rate, which would be constant in a self-preserving flow, increases with downstream distance : Kostovinos tentatively suggests an asymptotic spreading rate of 0.14, but the data are not incompatible with an indefinite increase of spreading rate.
