12-sensor probe designed to measure velocity and velocity gradient components (2mm measuring area) 12-sensor probe in a turbulent jet Phase averaged velocity vectors in a frame moving with the midplane mean velocity of a turbulent two-stream mixing layer. The color contours show the spatial distributions of the Reynolds shear stress and the turbulent kinetic energy dissipation rate. Measurements made by Rick Loucks for his Ph.D. dissertation. 35mm photo of the boundary layer in the Lyon wind tunnel taken by Jean-Louis Balint, Michel Ayrault and me. Visualized with dry incense smoke released from a slot in the wall and in the potential flow. A movie clip of this boundary layer can be see in the turbulence module of Multimedia Fluid Mechanics (2nd edition), Cambridge Univ. Press. Visualization of low-speed streaks in a turbulent boundary layer by Vincent Chiang using a scanning Laser light sheet and a high speed camera. A movie clip of this can be seen in the turbulence module of Multimedia Fluid Mechanics (2nd edition), Cambridge Univ. Press.

Field site on the Utah Salt flats SW of Salt Lake City where we made measurements in the surface layer for Alan Floz's dissertation. The 80'x120' test section of the NASA Ames wind tunnel. Our 12-sensor probe was lowered into the tunnel through the port indicated by the red arrow. During the experiment to investigate local isotropy of the vorticity field, the tunnel was otherwise empty. Vortices created by the flow past a rod on the wall of a boundary layer. Visualized with smoke released from a slot in the wall and illuminated by a laser light sheet. Dismantling our turbulence wind tunnel after 30 years of research to ship to Joe Klewicki at the University of New Hampshire. It is now reinstalled there.
