Dynamics of Smoke Transfer from a Localized Source by a Tornado-Like Vortex

The dynamics of a model impurity (smoke) transfer by a tornado-like vortex from a localized Source situated at the vortex core base has been experimentally studied in a closed chamber. It is established that a flow regime can exist in which the impurity mass transfer along the vortex core is accompanied by mass exchange between the core and Surrounding atmosphere. This exchange has the form of spiral formations ejected regularly out of the vortex core. This process takes place under stationary conditions at the chamber input and output, which implies an autoscillatory character of the flow in the system studied.
