  • Effects of swirl on intermittency characteristics in non-premixed flames 
    Ranga Dinesh, K. K. J.; Jenkins, Karl W.; Kirkpatrick, M. P.; Malalasekera, W. (Taylor & Francis, 2012-05-31)
    Swirl effects on velocity, mixture fraction, and temperature intermittency have been analyzed for turbulent methane flames using large eddy simulation (LES). The LES solves the filtered governing equations on a structured ...
  • Influence of bluff-body and swirl on mixing and intermittency of jets 
    Ranga Dinesh, K. K. J.; Jenkins, Karl W.; Savill, Mark; Kirkpatrick, M. P. (2010-09-30)
    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 ...
  • Investigation of the influence of swirl on a confined coannular swirl jet 
    Ranga Dinesh, K. K. J.; Kirkpatrick, M. P.; Jenkins, Karl W. (Elsevier Science B.V., Amsterdam., 2010-05-31)
    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 ...
  • Large Eddy Simulation of a turbulent swirling coaxial jet 
    Ranga Dinesh, K. K. J.; Savill, Mark A.; Jenkins, Karl W.; Kirkpatrick, M. P. (Inderscience, 2010-12-31)
    This work uses the Large Eddy Simulation (LES) technique to study velocity and passive scalar mixing along with intermittency of a spatially evolving turbulent coaxial swirl jet. The simulations captured the potential ...
  • LES Of intermittency in a turbulent round jet with different inlet conditions 
    Ranga Dinesh, K. K. J.; Savill, Mark A.; Jenkins, Karl W.; Kirkpatrick, M. P. (Elsevier, 2010-10)
    Large eddy simulation (LES) is a promising technique for accurate prediction of turbulent free shear flows in a wide range of applications. Here the LES technique has been applied to study the intermittency in a high ...
  • Study of jet precession, recirculation and vortex breakdown in turbulent swirling jets using LES. 
    Ranga Dinesh, K. K. J.; Kirkpatrick, M. P. (Elsevier, 2009-06)
    Large eddy simulations (LES) are used to investigate turbulent isothermal swirling flows with a strong emphasis on vortex breakdown, recirculation and instability behaviour. The Sydney swirl burner configuration is used ...
  • A study of mixing and intermittency in a coaxial turbulent jet 
    Ranga Dinesh, K. K. J.; Savill, Mark A.; Jenkins, Karl W.; Kirkpatrick, M. P. (Elsevier Science B.V., Amsterdam., 2010-04-30)
    A large eddy simulation study of mixing and intermittency of a coaxial turbulent jet discharging into an unconfined domain has been conducted. The work aims to gain insight into the mixing and intermittency of turbulent ...
