ABSTRACT
DUKLER 05.01. 1925 Newark NJ/USA 12.02. 1994 Houston TX/USA Abraham Emanuel Dukler obtained his BS from Yale University in 1945, his MS degree in 1950 and PhD degree in 1951 from University of Delaware, Newark DE. From 1945 to 1948 he was employed by an engineering office at Philadelphia PA; he was then until 1952 a research engineer with the Shell Oil Company at Houston TX, and from then joined University of Houston, Houston TX. First he was a faculty member within the Department of Chemical Engineering, from 1963 there professor of chemical engineering, department chairman from 1967 to 1973, and dean of engineering from 1976 to 1983. In parallel he was also Director, State of Texas Energy Council, from 1973 to 1975, and consultant to a number of firms in the oil industry. He was the recipient of the 1974 Research Award Alpha Chi Sigma, and of the 1989 Kern Research Award. He was from 1978 a Fellow of the American Institute of Chemical Engineers AIChE and was elected to the National Academy of Engineering in 1977. Dukler was known for his researches in two-phase flows involving gas and liquid, and gas and solid flows. He was also interested in film flow phenomena and in the flows of drops. His 1986 paper for example deals with the shape of the two-dimensional steady Taylor bubble as first described by Geoffrey Ingram Taylor (1886-1975), relating to the bubble rise in vertical channels. The inviscid treatment leads to an infinite set of shapes. Using experimental data, only one particular shape is finally retained. An integral mass and momentum balance analysis between the bubble free surface and the wall takes also viscous effects into account. Matching the two profiles at the nose results in a good description of the phenomenon. Anonymous (1976). A.E. Dukler. Mechanical Engineering 98(11): 86. P Anonymous (1985). Dukler, Abraham.
