    We have identified certain fundamental limitations of a mixing-length parametrization used in a popular turbulent kinetic energy-based subgrid-scale model. Replacing this parametrization with a more physically realistic ...
  • Neves, Theomar; Fisch, Gilberto; Raasch, Siegfried (Basel : MDPI AG, 2018)
    Using a high resolution model of Large Eddies Simulation (LES), named PALM from PArallel LES Model, a set of simulations were performed to understand how turbulence and convection behave in a pasture and forest sites in ...
  • El Guernaoui, Omar; Reuder, Joachim; Esau, Igor; Wolf, Tobias; Maronga, Björn (Dordrecht : Springer Netherland, 2019)
    We investigate the scaling for decaying turbulence kinetic energy (TKE) in the free-convective boundary layer, from the time the surface heat flux starts decaying, until a few hours after it has vanished. We conduct a set ...
  • Gebhardt, Cristian Guillermo; Romero, Ignacio (Heidelberg : Springer, 2020)
    This work proposes and investigates a new model of the rotating rigid body based on the non-twisting frame. Such a frame consists of three mutually orthogonal unit vectors whose rotation rate around one of the three axis ...
