BUEHLER

BUEHLER 09.05. 1910 Baraboo WI/USA 27.03. 1999 Knoxville TN/USA Robert ‘Bob’ Joseph Buehler was a graduate of the University of Wisconsin, Madison WI, with the BS and MS degrees in civil engineering. He then joined the Flood Control Branch of the Tennessee Valley Authority TVA for 41 years until 1975, following a mandatory retirement as branch chief. He from then was consultant and registered engineer in Tennessee. He was elected Fellow ASCE in 1978. Buehler’s 1969 ASCE paper deals with the numerical simulation of transient flows. During the past years major advances were made by TVA using digital computers to solve the basic differential equations for transient flow of water in open channels. The mathematical model employed used an explicit scheme to compute stage, discharge, and velocity transients from known initial and boundary conditions. Finite difference expressions of the governing equations of continuity and momentum were solved. Stage, discharge, local inflows, variable roughness along the channel, and the channel geometry can be used, resulting in discharges and stages along the channel for known initial conditions for both steady and transient flows. The results of this work indicate the diverse range over which the model was applied. There were two reservoirs, a natural river and an uncontrolled channel connection to the two reservoirs. Predictions agreed well with prototype measurements in all four cases considered. Other researches considered similar flow processes in TVA hydraulic structures, and were also involved in the monetary values of life and health. Buehler, B.J., Price, J.T., Garrison, J.M. (1968).

BULL 20.10. 1856 Bergen/N 18.11. 1907 Madison WI/USA Storm Bull was born in Norway. He graduated as a mechanical engineer in 1877 from the Polytechnic Institute, today’s ETH, Zurich. He then travelled extensively in Switzerland, Germany, Belgium, and France, visiting various shops and institutes, returned to Norway and there was for 2 years head draftsman in shipbuilding in the naval yard. In 1879 he moved to the United States, becoming in 1879 instructor in mechanical engineering at University of Wisconsin, Madison WI, and there was promoted in 1884 to assistant professor, then to professor of mechanical engineering in 1886, and in 1891 to professor of steam engineering, a position he held until his premature death due to a cancer of the stomach. Bull made contributions to the scientific and literary magazines, both in the USA and in Norway; his works showed marked talent and careful study. His main papers were published in the Engineering News Journal, where he was also a frequent contributor to its Engineering Literature Supplement. He authored the book Steam engineering, a widely used text in the USA in this field. During the 1900 Universal Paris Exhibition, he acted as vice-president of the Jury of Awards, whereas during the 1904 Louisiana Purchase Exposition, he was president of the Jury of Awards. He worked in addition with the State on various power and heating plants for institutions around Wisconsin. The Capitol Commission hired him in 1907 to complete plans and drawings for the Capitol heat and power plant equipment. He was member of the American Society of Mechanical Engineers ASME, the Western Society of Engineers, in which he won the Chanute Medal in 1903, and the Society for the Promotion of Engineering Education, acting as vice-president from 1901 to 1902.
