Design and Analysis of Liquid Hydrogen Technologies

Dr. Ahmad K. Sleiti research is focused on energy systems and thermofluids, with special interest in cryogenic refrigeration, liquefaction of H2 and NG, turbomachinery, Solid Oxide Fuel Cells, alternative energy, energy efficiency, CFD and experimental thermofluids. Dr. Sleiti obtained his Ph.D. degree in Mechanical Engineering from University of Central Florida. He has authored over 135 peer-reviewed papers in journals and conference proceedings, 2 book chapters and 3 patents. Dr. Sleiti has over 30 years of experience in industry and academia as expert, tenured faculty member and consultant. Dr. Sleiti is currently a professor of mechanical engineering at Qatar University. Previously he held an assistant and associate professor positions at UNC, ERAU and UCF in USA from 2001 to 2015. He also worked as senior engineer, project manager and consultant for high-ranked engineering firms and R&D corporations (SIGMA, PENTA GROUP, BETA, Siemens Energy, Electrodynamics, ASHRAE and others). Wahib A. Al-Ammari is currently working as a research assistant in Mechanical and Industrial Engineering Department at Qatar University. He obtained his BSc degree in Mechanical Engineering from Jordan University of Science and Technology. Al-Ammari has authored 25 papers published in high-impact factor journal, 5 conference proceedings papers, and 1 provisional patent. Al-Ammari has over five years of experience as a researcher in the field of renewable and non-renewable energy systems with focus on the solar energy applications, supercritical carbon dioxide power plants, CO2 capture and transportation, and cryogenic refrigeration and liquefaction systems. He also worked as a lecturer (3 years) in non-government academies in Jordan, which present several training courses for graduate and undergraduate students.
