Johann Nikuradse

Johann Nikuradse ( ივანე ნიკურაძე, Ivane Nikuradze; born November 20, 1894 in Samtredia, † July 18, 1979 ) was a Georgia -born, German engineer and physicist. Johann Nikuradse was the brother of Alexander Nikuradse, a physicist living in Germany and geopolitics, from which a close relationship with Alfred Rosenberg and a role in saving many Georgians during the Second World War are well known.

Life

Johann Nikuradse studied in Kutaisi. On the recommendation of the Dean of Tbilisi State University, Petre Melikishvili, he went for further studies in 1919 out of the country. 1921 completed the expansion of the Soviet system in Georgia to return to his country of birth and Nikuradse took German citizenship.

Nikuradse in 1920 a PhD student at Ludwig Prandtl and worked as a researcher at the Kaiser Wilhelm Institute for Flow Research later. In the early 1930s, acting under the National Socialist Factory Cell Organization of the Kaiser Wilhelm Institute for Flow Research, to spy for the Soviet Union and from the institute to steal books. This happened despite its strong ties to the Nazi Party. Prandtl defended him at first, but was eventually forced to release him in 1934. From 1934 to 1945 he was a professor at the University of Breslau, 1945, he was an honorary professor at the RWTH Aachen.

Nikuradse lived mainly in Göttingen and worked on hydrodynamics. His most famous experiment was published in 1933 in Germany .. Nikuradse carefully measure the friction in the flow experiments, as it sets in pressure lines at different speeds. He realized how drag coefficients of pipelines behave relative to the flow velocity.
