Local law-of-the-wall in complex topography: a confirmation from wind tunnel experiments [PDF]
, 2001 It is well known that in a neutrally-stratified turbulent flow in a deep constant-stress layer above a flat surface, the variation of the mean velocity with respect to the distance from the surface obeys the logarithmic law (the so-called ``law-of-the ...

A wind tunnel investigation of the shape of uncharged raindrops in the presence of an external, electric field [PDF]
, 1982 Results of a wind tunnel experiment in which electrically uncharged water drops of 500 to 3000 microns equivalent radius are freely suspended in the vertical air stream of the UCLA cloud tunnel are presented. During this suspension the drops were exposed

Temporal and Spatial Turbulent Spectra of MHD Plasma and an Observation of Variance Anisotropy [PDF]
, 2014 The nature of MHD turbulence is analyzed through both temporal and spatial magnetic fluctuation spectra. A magnetically turbulent plasma is produced in the MHD wind-tunnel configuration of the Swarthmore Spheromak Experiment (SSX).
