Abstract: The results of a series of measurements of centerline pressure deficit in tornado-like vortices are described. These measurements were undertaken for the purpose of determining 1) how the magnitude of the central pressure ...

Abstract: Measurements in a tornado simulator have yielded quantitative data on certain aspects of the mean flow of a variety of modeled vortices. The radius of maximum velocity in the vortex core has been measured using a hot-film ...

Abstract: Observations of vortices of various types produced in a large thermal plume are described. The apparatus used to generate the plume is the Météotron, an array of 105 fuel oil burners with a total heat output of approximately ...
