Instruction

Dr. Dudley Benton earned his degrees in mechanical engineering at Florida Atlantic University (BS, MS) and the University of Tennessee (PhD). His areas of research included heat exchanger design optimization and theoretical/experimental investigation of high temperature boiling on rough surfaces.

Dr. Benton has 27 years of industrial experience with thermodynamic cycles and combustion processes, including: fossil and nuclear power plants, air separation units, coal and flue gas desulfurization systems, boilers and condensers. He has dealt extensively with the analysis of evaporative and dry cooling towers, ground and surface water containment transport and long range environmental impact problems.

Dr. Benton also specializes in software development using modern computer languages and numerical methods. Comprehensive computer programs that he has developed include (i) steam and combined cycle codes; (ii) heat exchanger analysis codes that deal with single and two-phase flow, moisture separation, and mechanical characteristics involving stress, strain, tube macro deformation, and vibration; (iii) evaporative cooling tower codes, (iv) chemical reaction codes capable of handling non-ideal behavior, non-equilibrium states, and catalysts; and (v) several fluid flow and heat transfer codes.

Dr. Ralph Webb is Professor Emeritus of Mechanical Engineering at The Pennsylvania State University. He received his Ph.D. from the University of Minnesota and was Manager of Heat Research at The Trane Company for 15 years prior to joining Penn State. The courses he taught at Penn State include Two-Phase Heat Transfer, Heat Exchanger Design, Enhanced Heat Transfer, and Applied Heat and Mass Transfer. He also directed the research of many MS and PhD students at Penn State, has published many papers in the area of heat transfer enhancement, and has eight US patents on enhanced heat transfer surfaces. He is the author of Principles of Enhanced Heat Transfer, 2nd edition, Taylor & Francis, 2005.

Dr. Webb’s primary area of research is in the area of enhanced heat transfer. Applications that he has dealt with include boiling, condensation, fouling, air-cooled heat exchangers, electronic equipment cooling, and forced convection for gases. He has worked with many industrial companies to advance the heat transfer technology in their products. He has also taught numerous professional short courses on heat transfer enhance¬ment and heat exchanger design.

Dr. Webb is a recipient of the ASME Heat Transfer Memorial Award, the U.K. Refrigeration Institute Hall-Thermotank Gold Medal, and the AIChE Donald Q. Kern award. He is also a Fellow of ASME and ASHRAE and a Life Member of ASME. He is the Founding Editor and Editor-in-Chief of the Journal of Enhanced Heat Transfer and is an editor of Heat Transfer Engineering journal. He is a former technical editor of the ASME Journal of Heat Transfer and Applied Thermal Engineering and is Past Chair of the ASME Heat Transfer Division.
