Unsteady heat transfer caused by a confined impinging jet is studied using direct numerical
simulation (DNS). The time-dependent compressible Navier-Stokes equations are solved …

This article describes an investigation of flame shapes and flow configurations in a
premixed, swirl-stabilized dump combustor. High swirl, annular nozzle flows of this nature …

Direct numerical simulations of an unsteady impinging jet are performed to study momentum
and heat transfer characteristics. The unsteady compressible Navier–Stokes equations are …

Compared to the traditional modeling of computational fluid dynamics, direct numerical
simulation (DNS) and large-eddy simulation (LES) provide a very detailed solution of the …

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 …

The linear global stability of laminar buoyant jets and plumes is investigated under the low-
Mach-number approximation. For Richardson numbers in the range (plume) regimes. A …

The paper performs an investigation on multi-scale coherent structures that exist in different
flow patterns of triple interacting plumes. Time-averaged and turbulent flow characteristics …

A numerical study simulating the temporal vortical structures of a large-scale buoyant pool
fire has been carried out using a fully-coupled Large Eddy Simulation (LES) model which …

Plumes due to localized buoyancy sources are of wide interest owing to their prevalence in
many situations. This study investigates the transition from laminar to turbulent dynamics …

A near-field, unsteady buoyant plume exhibits puffing behaviour, characterised by the
periodic formation of large-scale vortical structures (puffs). It has been observed in numerical …
