    Abstract : Two codes have been developed and implemented for use on massively parallelsuper computers to simulate two-dimensional and quasi-geostrophic turbulence.The codes have been found to scale well with increasing resolution and width ofthe simulations. READ MORE

  4. 2. Numerical Investigation of Rotating and Stratified Turbulence

    Author : Enrico Deusebio; Erik Lindborg; Johan Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geostrophic turbulence; stable stratification; rotation; wall-bounded turbulence; gravity waves; atmospherical dynamics; direct numertical simulations; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Abstract : Atmospheric and oceanic flows are strongly affected by rotation and stratification. Rotation is exerted through Coriolis forces which mainly act in horizontal planes whereas stratification largely affects the motion along the vertical direction through buoyancy forces, the latters related to the vertical variation of the fluid density.

  5. 3. Numerical studies in rotating and stratified turbulence

    Author : Enrico Deusebio; Erik Lindborg; Gert-Jan van Heijst; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Although turbulence has been studied for more than five hundred years, a thorough understanding of turbulent flows is still missing. Nowadays computing power can offer an alternative tool, besides measurements and experiments, to give some insights into turbulent dynamics. READ MORE
