Omid Mahian has received his Ph.D. in Mechanical Engineering (Energy Conversion) and currently is a professor at School of Chemical Engineering, Xi'an Jiaotong University, China. Professor Mahian interests are solar desalination and application of nanotechnology for heat transfer enhancement that includes the increase of water evaporation rate. His Ph.D. dissertation was about the investigation of nanotechnology application for water evaporation rate enhancement in solar stills. He is currently an editorial board of Energy (Elsevier), Renewable Energy (Elsevier), senior associate editor of Journal of Thermal Analysis and Calorimetry (Springer) and associate editor of Journal of Thermal Science. He has published more than 150 peer reviewed articles in prestigious journals and serving as a potential reviewer in more than 100 international journals. Recently, he has focused on the methods for steam generation (water desalination) enhancement using nanoparticles. He has been selected as highly cited researcher since 2018. Somchai Wongwises is currently a Professor of Mechanical Engineering, Faculty of Engineering at King Mongkut's University of Technology Thonburi, Bangmod, Thailand. He received his Doktor Ingenieur (Dr.-Ing.) in Mechanical Engineering from the University of Hannover, Germany, in 1994. He has published more than 400 articles in archival journals and international conferences. His research interests include Renewable Energy, Gas-Liquid Two-Phase Flow, Heat Transfer Enhancement, and Thermal System Design. Professor Wongwises is the head of the Fluid Mechanics, Thermal Engineering, and Multiphase Flow Research Laboratory (FUTURE). Professor Wongwises has been selected as highly cited researcher since 2017.
