About the Authors
Dr. Robert J. Moffat is Professor Emeritus at Stanford University and former President of Moffat Thermosciences, Inc. Professor Moffat started his professional career at the General Motors Research Laboratories in the Gas Turbine Laboratory. He and a small group of engineers designed, built, and tested a high efficiency, two‐spool regenerative gas turbine that, starting from 30 below zero Fahrenheit, could deliver 350 HP in less than 2 minutes. He graduated from the University of Michigan and received his Master of Science at Wayne State University. Enrolling at Stanford University, he earned degrees in Mechanical Engineering as Master of Science, Engineer, and Ph.D. He became a Stanford professor and served as chairman of the Thermosciences Division for 13 years.
Professor Moffat’s research efforts have involved three areas: convective heat transfer in engineering systems, experimental methods in heat transfer and fluid mechanics, and biomedical thermal issues. His largest body of work concerns convective heat transfer. One program focused on gas turbine blade heat transfer. A second program aimed at convective cooling of electronic components covering forced, free and mixed convection. Several contributions arose including invariant descriptors, a new heat transfer coefficient for electronics cooling, and a simple correlation based on turbulence intensity.
His second area of research concerned experimental methods in the thermosciences namely full‐field imaging techniques for temperature, heat flux, and heat transfer coefficient measurement using thermochromic liquid crystals. He contributed regularly to the theory of uncertainty analysis. Dr. Moffat was an invited lecturer for 40 consecutive years in the Measurement Engineering Series, for more than 20 years in the Instrument Society of America Test Measurements Division and, for ten years in the ASME Professional Development program.
Dr. Moffat worked on biomedical engineering problems, in particular the thermal protection of newborn infants. He jointly developed a self‐contained, portable incubator which provided a neutral thermal environment for the infant while allowing free access by the attending physicians. Used on almost every continent where cold‐weather transport is needed, it received the ASME Holley Medal Award, 1987. He founded Moffat Thermosciences as a vehicle for consulting, research, and teaching in Heat Transfer and Experimental Methods. He delivered short courses in Electronics Cooling, Experimental Methods, and Uncertainty Analysis.
Dr. Roy W. Henk, professor in the Graduate School of Energy Science at Kyoto University, Japan, earned his bachelors degree at Virginia Tech and his masters and doctorate at Stanford University. Professor Henk taught courses within natural and experimental philosophy, currently known as classical physics and mechanical engineering.
Professor Henk’s experience includes industry, government labs, and academia. His work included wind tunnel tests at Virginia Tech and Japan’s Mach 5 tunnel at NAL, and water tunnels at the U.S. Naval Research Lab and at Stanford. He worked internationally in the aerospace industry, designing and testing advanced engine components with IHI (
