Paul Richard Heinrich Blasius

Who was Paul Richard Heinrich Blasius?

Paul Richard Heinrich Blasius was a German fluid dynamics physicist.

He was one of the first students of Prandtl who provided a mathematical basis for boundary-layer drag but also showed as early as 1911 that the resistance to flow through smooth pipes could be expressed in terms of the Reynolds number for both laminar and turbulent flow. After six years in science he changed to Ingenieurschule Hamburg and became a Professor. April 1, 1962 Heinrich Blasius celebrated his 50th anniversary and was active in teaching until he died on April 24, 1970.

One of his most notable contributions involves a description of the steady two-dimensional boundary-layer that forms on a semi-infinite plate that is held parallel to a constant unidirectional flow .
