Dear Colleagues,

Fundamental combustion research is a relatively young science. With the introduction of lasers and digital computers, effectively some 40 years ago, big steps could be made in understanding the physical and chemical details of combustion. At the moment the basics of combustion is quite well understood for traditional combustion problems. However, with the depletion of fossil fuels and the consequences of emissions and the anthropological green house effect, new challenges need to be tackled. Solid, liquid and gaseous fuels will be used due to their unrivaled energy density. Thus clean combustion concepts are required now and in the future. Advanced combustion technology will be needed to solve the problem of clean and efficient energy conversion to obtain electric and propulsive power.

To that end new combustion concepts are investigated all over the world. Think of fuel oxygen combustion, very lean premixed combustion, premixed charged compression ignition and chemical looping combustion systems, to name a few. Besides new clean combustion concepts also fuel flexibility plays an important role. In particular the use of hydrogen originating from any sustainable energy source like sunlight or biomass is a high potential energy carrier. This also holds for Fischer-Tropsch fuels originating from sustainable sources. Currently Carbon-Capture and Sequestration is regarded as a very promising (but temporal) technique if it is combined with the conversion of coal and biomass.

These challenges go along with the fact that nowadays high fidelity scientific methods are feasible to solve much of the peculiarities associated with the new fuels and combustion strategies. Laser-techniques and supercomputer calculations become more and more mature to unravel the problems that are mentioned. This issue of Energies will be dedicated to highly accurate analysis with the aid of advanced tools for understanding of advanced new (clean) combustion systems and/or combustion of alternative fuels. The goal of the current special issue will be to present a state-of-the-art in combustion science and technology for the future; the focus is on high fidelity assessment of promising solutions.

Abstract: Swirling reacting flows are widely used in many engineering applications to achieve mixing enhancement, flame stabilisation, ignition stability, and pollutant reduction. Since the current trend of swirl stabilised combustion systems is shifting towards lean burn combustion to satisfy new emission regulations, swirl stabilised complex flow structures and mechanisms that play a vital role in the flame dynamics are frequently encountered during the development stage of combustion systems. Extensive efforts have gone into performing numerical simulations and experimental investigations of swirl stabilised isothermal and reacting systems. Progress in computing power and modern experimental facilities have led to the expansion of numerical and experimental work to discover most critical issues in swirl stabilised combustion systems. This paper aims to provide a comprehensive review on the studies of flow and flame dynamics of swirl stabilised combustion systems using the state-of-the-art numerical simulations and experimentations.
