Welcome to the web site of Dr Jamel Orfi, Mechanical Engineering Department, King Saud University

Dr. Jamel Orfi obtained his B.A.Sc from Laval University, Canada in 1989 and his M.Sc.A and PhD Degrees from University of Sherbrooke, Canada in 1991 and 1995 respectively. All are in Mechanical Engineering. He worked as Mechanical Engineer with Ansaldo energia, as assistant Professor at the University of Moncton, New Brunswick, Canada and as Assistant, associate professor in Tunisia. He is on leave (full professor) from "Faculte' des Sciences de Monastir, Tunisia".

His research interests focus on desalination processes and thermodynamic analysis of thermal and desalination systems, on renewable energy applications (geothermal and solar) and on convective heat and mass transfer with evaporation and condensation. He developed several national and international collaborations and worked on projects in power and desalination, solar energy, evaporative cooling systems, and brine discharge problems. He has several publications on solar desalination and systems including a book chapter on modeling of a membrane distillation unit for desalination. Dr. Orfi is a member of KSU’s MED (Multiple Effect Distillation) technology transfer team collaborating with SWCC (Saline Water Conversion Corporation). Dr Orfi has been involved in teaching Thermal Sciences and Desalination to undergraduate and graduate students.
