Norbert Elsner (engineer)

from Wikipedia, the free encyclopedia

Norbert Elsner (born September 6, 1917 in Rauschwalde ; † November 17, 2001 in Dresden ) was a German engineer and professor of energy economics . His specialty was technical thermodynamics . He was vice dean and dean as well as a member of the Scientific Council of the Technical University of Dresden .

Live and act

Norbert Elsner was born in Rauschwalde in Silesia . From 1937 to 1942 he studied mechanical engineering at the Technical University of Wroclaw (TH Breslau) and obtained his degree in engineering (Dipl.-Ing.). He then worked from 1942 to 1945 as an assistant at the Institute for Piston Engines and Energy Economics at the Technical University of Wroclaw, and after the end of the war he changed to the chair for energy economics at the Dresden University of Technology until 1946 .

From 1946 to 1952 Elsner was conscripted and had to work on projects as part of the Soviet missile development in the Soviet Union.

After his return he was from 1952 assistant at Walther Pauer's Institute for Energy Economics at the TH Dresden . From the spring of 1953 he worked as a lecturer for technical heat theory and energy management. His doctorate took place in 1955.

Then he was appointed from 1956 as a professor with a teaching position for technical heat theory at the University of Transport in Dresden . In the summer of 1958 he returned to the TH Dresden as professor for energy economics and head of the institute for energy economics. In mid-1963 he was appointed professor for technical thermodynamics and director of the Institute for Thermodynamics and Energy Economics. He carried out this area of ​​responsibility until his retirement in 1983.

Elsner was considered an outstanding university professor among the students and employees. He held lectures on technical thermodynamics, heat transfer, chemical thermodynamics, energy management, heating, ventilation and air conditioning technology, which were known for their accuracy, methodological clarity and exemplary rhetoric.

In his research work he had a broad overview of the requirements of preliminary research in almost all energy-related fields. He dealt very intensively with water vapor research and published the first water vapor table in 1958. Furthermore, he dealt with the application of the 2nd law of thermodynamics for engineering process evaluations. In the GDR and beyond, he was seen as a pioneer in the introduction of exergetic evaluation.

The research carried out by Elsner in his institute was broad-based and included heating, drying and power plant problems. An expression of the academic performance of the Elsner School are the nearly 550 diploma students produced, 120 supervised or assessed dissertations as well as 11 appointments of his academic students to full professors, e.g. B. Wolfgang Fratzscher .

Elsner was also active for many years in academic positions such as vice dean and dean and as a member of the scientific council of the TU Dresden. In this way, he had a decisive influence on the scientific profile of the mechanical engineering faculty at the TU Dresden.
