**Bengt Sunden** received his M.Sc. in 1973, Ph.D. in 1979, and was appointed Docent in 1980, all at Chalmers University of Technology, Gothenburg, Sweden. He was appointed Professor of Heat Transfer at Lund University, Lund, Sweden, in 1992. He has served as Professor Emeritus and Senior Professor since 2016. His main research interests include heat transfer enhancement techniques, gas turbine heat transfer, and computational modeling and analysis of multiphysics and multiscale transport phenomena for fuel cells. He serves as Guest Professor of numerous prestigious universities. He is a Fellow of ASME, regional editor for *Journal of Enhanced Heat Transfer* since 2007, and associate editor of *Heat Transfer Research* since 2011, the ASME J. Thermal Science, Engineering and Applications (2010–2016), and ASME *Journal of Electrochemical Energy Conversion and Storage* since 2017. He is a recipient of the ASME Heat Transfer Memorial Award 2011 and Donald Q. Kern Award 2016. He received the ASME HTD 75th Anniversary Medal 2013. He has edited 30 books and authored three textbooks. He has published over 400 papers in numerous journals, with a h-index of 39 and over 6400 citations.

**Jin-yuan Qian** is presently Lecturer at the Institute of Process Equipment, College of Energy Engineering, Zhejiang University, China, a position he has held since his appointment in 2018. He received his B.Sc. and Ph.D. degrees, both in Chemical Process Equipment, from Zhejiang University, China, in 2011 and 2016, respectively. He was a joint Ph.D. student at TU Bergakademie Freiberg, Germany, from 2013 to 2014 and a Postdoc Researcher in the Department of Energy Sciences, Lund University, Sweden, from 2016 to 2017. His research interests include heat transfer, multiphase flow, flow control, and computational fluid dynamics. He has co-authored around 50 papers in international journals and conference proceedings.

**Junhui Zhang** is presently Research Professor at College of Mechanical Engineering, Zhejiang University, China, a position he has held since 2013, and has been Deputy Director of the State Key Laboratory of Fluid Power and Mechatronic Systems since 2019. He received his B.Sc. and Ph.D. degrees, both in Mechatronic Engineering, from Zhejiang University, China, in 2007 and 2012, respectively, and won the Outstanding Youth Science Foundation in 2019. His research interests are focused on the design and measurement of hydraulic components, especially the high-power-density axial piston pump. He has co-authored about 60 papers in international journals and conference proceedings.

**Zan Wu** is presently Senior Lecturer in the Department of Energy Sciences, Lund University, Lund, Sweden. He received his B.Sc. in Energy and Environmental System Engineering in 2008, and Ph.D. in Energy Engineering, both from Zhejiang University, Hangzhou, China. His research interests include multiphase flow, phase-change heat transfer enhancement techniques, microfluidics, surface modification, nanofluids, thermophysical properties, compact heat exchangers, and proton exchange membrane fuel cells. He has co-authored around 70 papers in international journals and conference proceedings as well as four book chapters.
