Well-defined and focused high-quality scientific/technical meetings dedicated to contacts between the academics and researchers in regional institutions of higher learning and their counterparts abroad are scarce. The purpose of starting a biannual international conference ideally to be rotated around the Middle East, Gulf, and North African region countries was and still is to meet this need and to provide a well-structured platform to boost research activity and productivity in the region as well as provide a point of contact and networking. Such a conference can serve as a focal point for the gathering of scientists and engineers who hail from this region and who are working abroad in Europe, North America, and other industrialized parts of the world. Thermal Engineering was selected as an umbrella title for the Conference series because of its encompassing meaning and because this research area is of great importance to the region. Topics related to environment, energy, petroleum, and construction are obvious examples of thermal engineering applications which are crucial to the economic development of the region.
