Oklahoma State Mechanical Engineering professor publishes his fourth book

Wednesday, January 19, 2022

Dr. Afshin J. Ghajar published his book, “Single- and Two-Phase Flow Pressure Drop and Heat Transfer in Tubes,”  Mechanical Engineering Series, Springer 2022.



The book provides in two parts a summary of three decades of pioneering research conducted by Ghajar and his students at Oklahoma State University on single- and two-phase flow pressure drop and heat transfer in tubes.  The first part summarizes the research conducted on different aspects of single-phase pressure drop and heat transfer in the transition region in plain horizontal macro, mini, micro tubes, and horizontal micro-fin tubes.  The second part describes the different issues related to two-phase gas- liquid flow in pipes with different orientations.


Ghajar is Emeritus Regents Professor and John Brammer Endowed Professor of  Mechanical Engineering and Aerospace Engineering at Oklahoma State University.  He received his BS, MS, and PhD degrees all in mechanical engineering from OSU. He is a renowned expert in the thermal and fluids field, focusing on experimental heat transfer/fluid mechanics and development of practical engineering correlations.


Ghajar is a Fellow of the American Society of Mechanical Engineers (ASME) and the American Society of Thermal and Fluids Engineers (ASTFE).  He is a Registered Professional Engineer in the State of Oklahoma. He has received countless teaching/service awards, such as the 75th Anniversary Medal of the ASME Heat Transfer Division, the ASME ICNMM Outstanding Leadership Award, and the Donald Q. Kern Award, among others.


Ghajar’s research work has resulted in over 250 publications including professional journals, reports, books, peer-reviewed conference papers or symposium proceedings.  His research achievements have also been documented by a large number of presentations as well keynote and invited lectures all over the world.  As of 2022, his research has been cited more than 7500 time.  A 2020 study conducted by Ionnidis et al. of Stanford University
Updated science-wide author databases of standardized citation indicators ( nearly 160,000 scientists of all disciplines based on citations to their work over their career and for the year 2019, Professor Ghajar ranked in the top 1.3% of researchers in Mechanical Engineering and Transports category.


Ghajar currently serves as the Editor-in-Chief of Heat Transfer Engineering Journal and is the Heat Transfer Series Editor for CRC Press (he has edited 13 books to date).  He is the co-author of two popular textbooks, Heat and Mass Transfer – Fundamentals and Applications, 6th Edition (2020), and Fundamentals of Thermal-Fluid Sciences, 6th Edition (2022), both published by McGraw-Hill; and the author of Two-Phase Gas-Liquid Flow in Pipes with Different Orientations, Springer Briefs in Applied Sciences and Technology, published by Springer 2020.
