Premixed and partially premixed turbulent flames are widely used for energy conversion in land transportation (e.g., spark ignition engines in cars), aviation (e.g., aero-engine afterburners), and stationary power generation (e.g., gas turbines). Therefore, present environmental and efficiency challenges call urgently for new solutions that satisfy stringent requirements for ultra low-emission and highly efficient combustion technology. To make a breakthrough in this area, both fundamental and applied studies of numerous unresolved issues relevant to premixed turbulent flames are strongly necessary.

The special issue will become an international forum for researchers to summarize the most recent developments and ideas in the field, with the special emphasis given to experimental, numerical, and theoretical results obtained within the past five years. The topics to be covered include, but not limited to:

• New diagnostic methods and approaches for investigating premixed turbulent flames
• Experimental data base for testing combustion models
• Direct numerical simulations of premixed turbulent flames
• New turbulence-combustion interaction models for RANS and LES applications
• Benchmark theoretical solutions
• Turbulent flame displacement speed, burning velocity, and mean flame brush thickness
• Temporal and spatial development of premixed turbulent flames
• Flame instabilities
• Highly turbulent combustion including flame quenching
• Lewis number and preferential diffusion effects in turbulent flames
• Combustion under elevated pressures
• Flame-generated turbulence
• Scalar transport in premixed turbulent flames
• Detailed chemistry and premixed turbulent combustion
• Ignition of turbulent mixtures
• Turbulent flames in internal combustion engines
• Partially premixed turbulent combustion
