LEMOS extensions

The LEMOS package provides additional tools and methods for OpenFOAM, including

 

Turbulence Modeling

 

  • LES filter:

    • nonlinear filter (median, maximum, minimum)
    • linear filter (gaussian mean, arithmetic mean)
    • differential filter

  • LES turbulence modeling:

    • dynamic mixed SGS model (Zhang, Vreman) with extension to scalar transport  
    • dynamic mixed version of Meneveau's lagrangian turbulence model with extension to scalar transport

  • HYBRID turbulence modeling:

    • hybrid kOmegaSST - dyn. Smagorinsky model
    • hybrid V2F - dyn. Smagorinsky model

  • PANS turbulence modeling:

    • kEpsilon model



Mesh 

  • mesh motion solver based on radial basis function (port from OF 1.6-ext)



Pre-processing

  • inflow generator for synthesis of turbulent fields with prescribed second order statistics using turbulent spot method (in-house development)
  • POD analysis tool (port from OF 1.6-ext)



Post-processing

  • function object to calculate friction velocity uTau
  • function object to calculate energy dissipation rate
  • LambdaCI criterion
