Richardson and Reynolds number effects on the near field of buoyant plumes: temporal
variability and puffing Page 1 J. Fluid Mech. (2022), vol. 950, A24, doi:10.1017/jfm.2022.788 …

Flickering buoyant diffusion methane flames in weakly rotatory flows were computationally
and theoretically investigated. The prominent computational finding is that the flicker …

The vorticity dynamics of turbulent, buoyant, and pure plumes released into the quiescent
ambience has been investigated using large-eddy simulations with plume Reynolds number …

Fire accidents might be caused by liquid fuel leakage, which can accumulate in a prescribed
area under the action of physical barriers. Therefore, pool fires could be of an arbitrary …

The physical characteristics and evolution of a large-scale helium plume are examined
through a series of numerical simulations with increasing physical resolution using adaptive …

Buoyant plumes often pulsate, or puff, at a characteristic frequency that depends on the
Richardson number. In many engineering and natural applications, however, interactions …

Ammonia is one of carbon-neutral hydrogen derivatives and is identified as a sustainable
fuel for mobile applications. However, the combustion instability of pure ammonia remains a …

The emergence of collective dynamical behaviors in a complex system has distinct
properties that its individuals do not have on their own. In the study, a series of circular …

This study computationally investigates small-scale flickering buoyant diffusion flames in
externally swirling flows and focuses on identifying and characterizing various distinct …

The near-field characteristics of highly buoyant plumes, commonly referred to as lazy
plumes, remain relatively poorly understood across a range of flow conditions, particularly …
