High Speed Imaging Near Surfaces
High repetition rate laser sources and high frame rate digital cameras enabled the development of new diagnostics capabilities that moved combustion research into a new domain. The ability to observe flow and reactions in time and space at relevant scales provides insights that allow validation and development of ever more predictive simulations.
Amongst many aspects in combustion, especially in technical devices, increased attention must be paid to near-surface processes. This is important to understand flame quenching and heat transfer. Improving our ability to model heat transfer for transient conditions under high-pressure and high temperature conditions such as in internal combustion engines is critically important for the development of next generation engines.
This talk will present the development of several 2D and 3D high-speed imaging tools and illustrate their use for measurements in internal combustion engines and generic experimental setups.

Challenges for Aviation Engines – A Combustion Point of View
The presentation will focus on future combustion product opportunities and innovation challenges for small aero engines. Externally set environmental goals and expected future environmental regulations will be addressed. Technology strategies to address the innovation challenges, in collaboration with suppliers, research institutions, and universities will be discussed.

Low Emissions, Fuel Flexible Combustion for Power Systems and Process Heating
Combustion will continue to be the dominant process by which stored energy is released for practical use in process heating and power systems for many decades to come. Burners, gas turbine combustors, and reciprocating piston engines all have played and will continue to play a role in process heating, power production and mechanical drive applications. Modern generations of such systems have already significantly reduced pollutant emissions. However, the careful balance between low emissions and operational efficiency often requires that systems be optimized for a single, dedicated fuel.
In the paper the following, three-prong hypothesis is postulated: 1) homogenous charge compression ignition (HCCI) mode of combustion and flameless oxidation (combustion) occupy the same region in turbulent combustion phase diagram, namely the broken (fragmented) reaction zone, 2) internal partial fuel reforming is a key process behind the ultra-low NOx emissions from both processes, 3) internal fuel reforming can be adopted in HCCI engines and turbine combustors as means of combustion and emissions control.
