Saddled with the task of improving a machine to remove shavings, he found that no matter how low a fluid's viscosity was, the fluid would always remain stationary at the walls of the pipe.

Glauert, his name graces a phenomenon in which "clouds" condense around a supersonic (*) airplane's jet intakes, wings and shockwaves caused by the plane's breaking of the sound barrier. With his most famous student, Theodore von Karman, he discovered that vortices could induce drag, leading to a revolution in aircraft design. FTP, name this "father of aerodynamic theory," whose namesake dimensionless number is the ratio of a fluid's viscosity to its thermal conductivity.
