LEE C.A. 16.11. 1915 Laramie WY/USA 20.06. 1995 Knoxville TN/USA Charles Allen Lee obtained the BS degree in civil engineering from University of Wyoming, Laramie WY, and the MS degree from Lehigh University, Bethlehem PA, in 1940. He was then a hydraulic engineer at the David Taylor Model Basin, Navy Department, Washington DC, in the 1940s, later from 1948 to 1958 Chief of the Paper and Tissues Development Process, Neenah WI, and in 1959 he founded the Charles A. Lee Assocs. Inc., Knoxville TN, of which he was owner and president. Lee was member of the American Society of Civil Engineers, and winner of its 1950 Collingwood Prize. He was also recipient of the Award TAPPI, the leading association for the worldwide pulp, paper, packaging, and converting industries of paper. The 1949 paper is concerned with model tests conducted at David Taylor Model Basin on the cross-sectional dimensions and the design of bends for Panama Canal. The study includes: (1) Effect of variable cross-sectional dimensions for both one-way and twoway traffic; (2) The comparative handling characteristics of various types of ships under specific conditions; (3) Effect of canal currents on the handling characteristics of ships; and (4) Comparison of bend types. The tests were conducted in a large laboratory facility with a scale factor of 1:50. The 1957 paper deals with the transition on a smooth flat plate in a zero pressure gradient using the then conventional surface tube, and hotwire techniques. It was shown that the laminar oscillations occurring with the laminar layer stability play an important role in the transition phenomenon. It was demonstrated that the development of a turbulent wake from a vortex street governs the transition flow pattern. It was found that a higher turbulence level invokes no laminar oscillations. Lee also invented a dewatering system, separating solids from a slurry in 1980. Anonymous (1950). C.A. Lee, Collingwood Prize winner. Civil Engineering 20(10): 675. P Anonymous (1977).
