      Agromayor Otero, Roberto (Master thesis, 2017)
      Rankine Cycles are an effective and efficient manner to convert waste thermal energy into power. Numerous fluids can be used in Rankine cycles, including water, hydrocarbons, hydrofluorocarbons, siloxanes, alcohols or even ...

    • Turbophoresis in forced inhomogeneous turbulence 

      Mitra, Dhrubaditya; Haugen, Nils Erland L; Rogachevskii, Igor (Journal article; Peer reviewed, 2018)
      We show, by direct numerical simulations, that heavy inertial particles (characterized by Stokes number St) in inhomogeneously forced statistically stationary isothermal turbulent flows cluster at the minima of mean-square ...

    • Turborundkjøring som erstatning av dagens rundkjøring i Leirgrovvika 

      Stonys, Andrius (Master thesis, 2018)
      Krysset i Leirgrovvika er utformet som rundkjøring. Krysset knytter europa- og fylkesveg, via en trearmet rundkjøring. Geografisk ligger rundkjøringen i et relativt flatt terreng. Dette er første krysset som blir brukt av ...

    • Turbulence measurements with fixed and floating profiling wind lidar 

      Kelberlau, Felix (Doctoral thesis, 2020)
      Knowledge about turbulence in the wind helps estimate and optimize the profitability of wind turbines. Light detection and ranging (lidar) is a cost-efficient, flexible, and accurate remote sensing technology for measuring ...

    • Turbulence modeling of transverse flow on ship hulls in shallow water 

      Jakobsen, Ken-Robert Gjelstad (Doktoravhandlinger ved NTNU, 1503-8181; 2010:174, Doctoral thesis, 2010)
      The hydrodynamic forces acting on a ship that travels in restricted water vary greatly with water depth and the geometry of the ship hull. This will affect the ship maneuverability in terms of various flow effects like for ...

    • Turbulence Modelling of the Flow Around a Prolate Spheorid 

      Larssen, Henrik Stumberg (Master thesis, 2018)
      In numerous engineering disciplines, including naval and offshore engineering, the accurate prediction of turbulent flows is essential for cost-efficient and safe designs. For industrial applications, the turbulence must ...

    • Turbulent channel flow of generalized Newtonian fluids at a low Reynolds number
