Gary Settles’ Schlieren Films

Prof. Settles grew up on a farm in eastern Tennessee. His interest in fluid dynamics, optics, and experiments began in his teen years with the construction of miniature subsonic and supersonic wind tunnels, the latter of which won awards at the 1967 International Science Fair and was featured in the Amateur Scientist section of Scientific American magazine. He gained industrial and laboratory experience through summer appointments at the US Naval Ordnance Lab, NASA’s Ames Research Center and the Boeing Company, where he worked on both 747 and SST aerodynamics. He studied at the University of Tennessee under an Alcoa Foundation scholarship, receiving the Bachelor of Science Degree with honors in Aerospace Engineering in 1971. Settles book, entitled Schlieren and Shadowgraph Techniques, was published by Springer-Verlag in September 2001. (PSU Gas Dynamics Lab)
