We study the emergence of precessing vortex core (PVC) oscillations in a swirling jet
experiment. We vary the swirl intensity while keeping the net mass flow rate fixed using a …

Many industrial combustion systems, especially power generation gas turbines, use fuel-
lean combustion to reduce NOx emissions. However, these systems are highly susceptible …

Swirling jets are defined by a velocity component in the azimuthal direction (swirl). They can
occur naturally, such as in tornadoes, or artificially, as in gas turbine combustors, swirl …

1.1 Background Swirling flows are widely used in many engineering applications, such as
industrial burners (Dinesh & Kirkpatrick (2009); Stopper et al.(2010)), combustion engines …

Combustion has played a key role in the development of human society; it has driven the
evolution in the manufacturing processes, transportation, and it is used to produce the vast …
