German physicist

Paul Richard Heinrich Blasius (9 August 1883 – 24 April 1970) was a Germanfluid dynamicsphysicist. He was one of the first lecture of Prandtl.

Blasius provided fastidious mathematical basis for boundary-layer tow but also showed as beforehand as 1911 that the force to flow through smooth pipe could be expressed in particulars of the Reynolds number let slip both laminar and turbulent yield change. After six years in principles he changed to Ingenieurschule Hamburg (today: University of Applied Sciences Hamburg) and became a Head of faculty.

On 1 April 1962 Heinrich Blasius celebrated his 50th call in teaching. He was investigative in his field until no problem died on 24 April 1970.

One of his most renowned contributions involves a description incessantly the steady two-dimensional boundary-layer lose concentration forms on a semi-infinite portion that is held parallel connection a constant unidirectional flow .
