Paul Richard Heinrich Blasius

Heinrich Blasius ( born August 9, 1883 in Berlin, † April 24, 1970 in Hamburg ) was a German physicist and university teacher. His field was the fluid mechanics. According to him, the similarity solution of the incompressible plate boundary layer is named.

Life

Heinrich Blasius was born in 1883 in Berlin. In the years 1902-1906 he studied in Marburg and Göttingen. He was one of the first PhD students at Ludwig Prandtl. During this time his works were to the boundary layer. After six years of research, he moved in 1912 to the Hamburg School of Engineering (now the University of Applied Sciences Hamburg) and devoted himself entirely to teaching. Heinrich Blasius celebrated on April 1, 1962 its 50th anniversary of service and taught there until his death on 24 April 1970.

Work

As part of his scientific work, Blasius dealt with the mathematical treatment of the boundary layer equations. He was able to show that the frictional resistance of a pipe flow can be expressed by the Reynolds number. He is known especially for the similarity solution of the boundary layer along the flat plate without pressure gradient, which is referred to in his honor as a Blasius boundary layer. During his research he published, among other things:

  • Boundary layers in fluids with small friction, Teubner Verlag, 1907
  • Laminar flow in channels of varying width, Journal of Mathematics and Physics, 1910
  • The law of similarity in friction processes in liquids, Forschg. Arb Ing - Wes, 1913
