More than 150 combustion researchers from all over Saudi Arabia and the surrounding regions came in to KAUST to discuss all matters related to combustion science. Held on the 21 and 22 May, the meeting featured four invited lectures and 39 oral presentations across four different technical sessions and 20 poster presentations.
Energy Demand in the Transportation Sector

Compositional Inhomogeneties in Turbulent Flames
Prof. Assad R. Masri from the School of Aerospace, Mechanical and Mechatronic Engineering, The University of Sydney, Australia; gave the second invited talk of the day. He reviewed the recent advances in the field of Compositional inhomogeneity with particular focus on the Sydney piloted burner with compositionally inhomogeneous inlets.
This burner was recently introduced as an ideal platform featuring mixed-modes of combustion and showing enhanced stability with varying gradients of mixture fraction at the inlet. This and other characteristics of the flames with enhanced stability are now a challenge to modellers worldwide.
CO2 Capture and Utilization Technologies
The third invited talk was by Dr. Aqil Jamal from the Carbon Management R&D Division, Saudi Aramco Research and Development Center, Saudi Arabia. He discussed the recent trends in CO2 capture and utilization technologies which is a key technology platform to enable deep reduction of greenhouse gases while meeting the growing global energy demand.
“Power plant and process industries are the two biggest sectors where large amounts of CO2 can be captured in a cost-effective manner for further utilization or underground storage. Recent advances in material science offer new opportunities for economically feasible CO2 capture and utilization in combination with renewable energy. ” He said.
He introduced the latest innovative materials and approaches to capture and utilize CO2 from industrial point sources and highlight key carbon capture and utilization technologies under development at Saudi Aramco.
Effects of Flow Turbulence and Fuel Type on the Structure and Blowoff Characteristics of Bluff-Body Stabilized Lean Premixed Flames
The final invited talk of the meeting was by Prof. Baki M. Cetegen, Department of Mechanical Engineering, University of Connecticut, Storrs, CT
He enumerated in detail about his study of the structure of unconfined, lean premixed, bluff body stabilized flames for different levels of turbulence intensity in the approach flow and different fuels (methane, propane, ethylene).
Lean flame blowoff equivalence ratio dependence on fuel type and turbulence conditions was also discussed in view of the laser-based measurements. The experimental results from this canonical flame configuration are being used for validation of LES simulations.
