This paper presents experimental studies of the structures and burning velocities of
premixed ammonia/air jet flames at high Karlovitz (Ka) number conditions. Simultaneous …

Turbulent premixed flames subjected to extreme levels of turbulence exhibit reaction zone
broadening and thinning. Instantaneous flame structures visualized using advanced laser …

A new compact active turbulence generator is developed, tested, and characterized, which
extends the capabilities of such generators used in turbulent premixed combustion research …

A discrepancy between the enhancement in overall burning rate and the enhancement in
flame surface area measured for high-intensity turbulence is addressed. In order to reconcile …

We investigate the possibility of determining the local turbulent flame speed by measuring
the individual terms in the balance of a mean progress of reaction variable for the case of a …

Staged combustion technology is widely applied in modern low-emission energy and power
systems. This study employs large eddy simulations (LES) to investigate the flame dynamics …
