Efstathios E. (Stathis) Michaelides, PhD, is currently the holder of W.A. (Tex) Moncrief Chair of Engineering at Texas Christian University (TCU) and also a Fellow of the Ralf Lowe Energy Institute at TCU. He is recognized as a leading scholar in the areas of multiphase flows and energy conversion, where he has authored seven monographs. He has published more than 170 journal papers and has contributed more than 250 presentations in national and international conferences. He chaired the Fourth International Conference on Multiphase Flows (New Orleans May 27 to June 1, 2001). He was awarded an honorary M.A. degree from Oxford University (1983); the ASEE Centennial Award for Exceptional Contributions to the Profession of Engineering (1993); the Lee H. Johnson award for Teaching Excellence (1995); the Senior Fulbright Fellowship (1997); the ASME Freeman Scholar award (2002); the Outstanding Researcher award at Tulane University (2003); the ASME Outstanding Service award (2007); the ASME Fluids Engineering award (2014); the ASME-FED Ninetieth Anniversary Medal (2016); and the ASME Edwin F. Church Medal for "eminent service in increasing the value, importance and attractiveness of mechanical engineering education."
Martin Sommerfeld, Dr.-Ing., studied at the Technical University of Aachen, where he received his doctorate in 1984. Thereafter, he conducted research at the Department of Aeronautical Engineering, Kyoto University, Japan, with a research fellowship obtained from the Japan Society for Promotion of Science and the Alexander von Humboldt Foundation. At the Institute of Fluid Mechanics of the University of Erlangen, he headed a research group on two-phase flow from 1986 to 1994 and completed his habilitation. In October 1994 he was appointed as Professor of Mechanical Process Engineering at the Martin-Luther-University of Halle-Wittenberg. In 1997 he received the DECHEMA Award 1996 for his contributions to multiphase flow measurements, modelling, and numerical prediction. Since 2017 he is Professor at the Otto-von-Guericke University Magdeburg in the Faculty Process and Systems Technology, leading the Institute Multiphase Flow Systems. Professor Sommerfeld has organized a continuing series of workshops on two-phase flow predictions, ASME symposia, the International Conference on Multiphase Flow (ICMF 2007), and several other international conferences. For 15 years Professor Sommerfeld has organized jointly with ERCOFTAC the "Best Practice Guidance Seminar CFD for Dispersed Multi-Phase Flows." He has published 220 journal publications and more than 210 conference papers as well as 40 contributions to monographs. His present research activities on multiphase flows are related to modelling of particulate flows through experimental analysis using modern optical methods and direct numerical simulation for extending Euler/Lagrange numerical methods with applications range from particulate flows in transport lines over spraying systems and reactive bubbly flows to particle-laden flows in bio-medical systems.
Berend van Wachem, PhD, is currently Chair of Mechanical Process Engineering at the Otto-von-Guericke University in Magdeburg, Germany. His main research areas comprise multiphase flow, particle technology, numerical methods, and computational fluid dynamics. He has published more than 100 scientific journal papers on these topics and has contributed to more than 150 presentations at conferences on these topics. He is also the main developer of the software package that may be accessed at www.multiflow.org, to predict the behavior of multiphase flows. He holds a PhD degree from Delft University of Technology and was Professor at the Imperial College London prior to moving to Magdeburg, Germany. In his free time, he enjoys rowing, and he is the proud father of twin daughters.
