We are very happy to announce the following keynote speakers for the  5th International Conference on Multiphase Flow and Heat Transfer (ICMFHT'20) :



Afshin J. Ghajar

Dr. Afshin J. Ghajar
Oklahoma State University, USA
Keynote Speaker

Dr. Afshin J. Ghajar is Regents and John Brammer Endowed Professor in the School of Mechanical and Aerospace Engineering at Oklahoma State University, Stillwater, Oklahoma, USA and an Honorary Professor of Xi’an Jiaotong University, Xi’an, China. He received his BS, MS, and PhD all in Mechanical Engineering from Oklahoma State University. His expertise is in experimental heat transfer/fluid mechanics and development of practical engineering correlations. Dr. Ghajar has made significant contributions to the field of thermal sciences through his experimental, empirical, and numerical works in heat transfer and stratification in sensible heat storage systems, heat transfer to non-Newtonian fluids, heat transfer in the transition region, and non-boiling heat transfer in two-phase flow. His current research is in two-phase flow heat transfer/ pressure drop studies in pipes with different orientations, heat transfer/pressure drop in mini/micro tubes, and mixed convective heat transfer/pressure drop in the transition region (plain and enhanced tubes). Dr. Ghajar has been a Summer Research Fellow at Wright Patterson AFB (Dayton, Ohio) and Dow Chemical Company (Freeport, Texas). He and his co-workers have published over 200 reviewed research papers and 10 book/handbook chapters. He has delivered numerous keynote and invited lectures at major technical conferences and institutions.

He has received several outstanding teaching, research, advising, and service awards from College of Engineering at Oklahoma State University. His latest significant awards are the 75thAnniversary Medal of the ASME Heat Transfer Divisionin recognition of his service to the heat transfer community and contributions to the field“, awarded in 2013, the ASME ICNMM 2016 Outstanding Leadership Award, this award recognizes a person whose service within the ICNMM (International Conference on Nanochannels, Microchannels, and Minichannels) is exemplary; and the 2017 Donald Q. Kern Award “in recognition of his outstanding leadership in the field of heat exchangers and two-phase flow, book and archival publications, and service to the academic and industrial professionals”. Dr. Ghajar is a Fellow of the American Society of Mechanical Engineers (ASME), Heat Transfer Series Editor for CRC Press/Taylor & Francis (he has edited ten books to date), and Editor-in-Chief of Heat Transfer Engineering, an international journal published twenty times per year by Taylor and Francis. Heat Transfer Engineering is aimed at practicing engineers and specialists in heat transfer. Dr. Ghajar is also the co-author of the 6th Edition of Cengel and Ghajar, Heat and Mass Transfer – Fundamentals and Applications, McGraw-Hill, 2020. The 6th edition was published in April 2019.

Topic of Keynote: Two-Phase Gas-Liquid Flow in Pipes with Different Orientations


Dr. Gretar Tryggvason

Dr. Gretar Tryggvason
Johns Hopkins University, USA
Keynote Speaker

Gretar Tryggvason is the Charles A. Miller, Jr. Distinguished Professor at the Johns Hopkins University and the head of the Department of Mechanical Engineering. He received his PhD from Brown University in 1985 and was on the faculty of the University of Michigan in Ann Arbor until 2000, when he moved to Worcester Polytechnic Institute as the head of the Department of Mechanical Engineering. Between 2010 and 2017 he was the Viola D. Hank professor at the University of Notre Dame and the chair of the Department of Aerospace and Mechanical Engineering.
Professor Tryggvason is well known for his contributions to computational fluid dynamics; particularly the development of methods for computations of multiphase flows and for pioneering direct numerical simulations of such flows. He served as the editor-in-chief of the Journal of Computational Physics 2002-2015, is a fellow of APS, ASME and AAAS, and the recipient of several awards, including the 2012 ASME Fluids Engineering Award and the 2019 ASTFE Award.
