Josef Alexander Kozeny (February 25, 1889 – April 19, 1967) was an Austrian hydraulic engineer and physicist. Today he is mainly remembered for the Kozeny–Carman equation which describes fluid flowing through a packed bed of solids.[1]
Born in Josefstadt, Bohemia, Kozeny moved to Prague to study at the German Technical University. He later moved to Vienna to study at the University of Agricultural Sciences.[2]
In 1922, he was appointed professor at the University of Tartu in Estonia.In 1924, he became a professor at the University of Agricultural Sciences in Vienna.[2] [3] In 1929 he got a second habilitation, this time at College of Technology (TH Wien), now TU Wien.Since 1930 he had lectures at TH Wien.[3] In 1935 he lectured „Wasserbau III - Anlagen des städt. Tiefbaus und ldw. Wasserbau“, „Enzyklop. der Ing.wissenschaften für Architektur“ and „Enzyklop. der Ing.wissensch. für Vermessungswesen“ at TH Wien.[3] [4] [5] On the first January 1940 he got German: außerordentlicher Professor, of Hydraulics and Hydraulic Engineering („Verkehrswasserbau, städt. Tiefbau und ldw. Wasserbau“) at TH Wien.[3] On the first of February 1941 he got German: ordentlicher Professor at TH Wien.[3] He was designated Professor Emeritus in 1959.[2]
He became a member of the Austrian Academy of Sciences in 1958 and received an honorary doctorate in 1965.
Kozeny published a textbook, “Hydraulics”, in 1953, a book which became a standard in the field. He was best known for his contribution to the Kozeny-Carman equation. Used to calculate the flow of a liquid through a packed bed of solids, the equation was first proposed by Kozeny in 1927 and later modified by Philip Carman.[6]
