  • A comparison of modified K-ε turbulence models for buoyant plumes 
    Worthy, Jude; Sanderson, V. E.; Rubini, Philip A. (Taylor and Francis, 2001-02-01)
    The effect of buoyancy on the production and dissipation of turbulent kinetic energy is investigated in variants of the popular k- ε turbulence model. The standard gradient diffusion model is considered for the scalar ...
  • Large eddy simulation of buoyant plumes 
    Worthy, Jude (Cranfield UniversitySchool of Engineering, 2003-05)
    A 3d parallel CFD code is written to investigate the characteristics of and differences between Large Eddy Simulation (LES) models in the context of simulating a thermal buoyant plume. An efficient multigrid scheme is ...
  • A Study of LES Stress and Flux Models Applied to a Buoyant Jet. 
    Worthy, Jude; Rubini, Philip A. (Taylor and Francis Ltd, 2005-09-03)
    Large eddy simulation (LES) stress and scalar flux subgrid scale models are evaluated in the context of buoyant jets. Eddy viscosity, eddy diffusivity (including formulations of the generalized gradient diffusion hypothesis), ...
