Non-linearities in the thermoacoustic response of a premixed swirl burner [PDF]
PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...

Investigation of the influence of swirl on a confined coannular swirl jet [PDF]
Large Eddy Simulations are used to model a turbulent confined coannular combustor and examine the effects of swirl on the flow field and mixing. Three separate simulations with relatively high mesh resolutions and different swirl numbers have been ...

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]
Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

3D Numerical Simulation and Performance Analysis of CO2 Vortex Tubes
In view of the extensive application of swirl flow pipes (vortex tubes) in refrigeration systems, the parameters of swirl flow pipes were investigated to provide optimal cooling and heating conditions. Three-dimensional numerical simulations were carried

Influence of bluff-body and swirl on mixing and intermittency of jets [PDF]
In this paper we present the modelled results of turbulence, scalar mixing and intermittency for three different basic fluid dynamical problems using large eddy simulation (LES). The modelled problems are a turbulent round jet, a bluff body stabilised

Study of jet precession, recirculation and vortex breakdown in turbulent swirling jets using LES. [PDF]
Large eddy simulations (LES) are used to investigate turbulent isothermal swirling flows with a strong emphasis on vortex breakdown, recirculation and instability behaviour.
