  4. 2. A Study of Turbulent Natural Convection Boundary Layers Using Large-Eddy Simulation

    Author : Darioush Gohari Barhaghi; Chalmers tekniska högskola; []
    Keywords : natural convection boundary layer; DNS; LES; radiation heat transfer; free convection; cavity; vertical cylinder;

    Abstract : The structure of turbulent natural convection boundary layers in differentgeometries and the effect of the buoyancy on a mixed convection boundarylayer are investigated. These geometries comprise a vertical finitecylinder, a vertical infinite channel, a cavity and a vertical finite channel. READ MORE

  5. 3. Turbulence Measurements in a Natural Convection Boundary Layer and a Swirling Jet

    Author : Abolfazl Shiri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirl; constant current bridge; high Rayleigh number; natural convection; Jet; cold-wire thermometry; vertical cylinder; laser Doppler anemometry; turbulent boundary layers;

    Abstract : Two sets of experimental measurement were carried out on an axisymmetric swirling jet flow and a natural convection boundary layer. In the first experiment, the far field of an incompressible swirling jet, discharged into a quiescent ambient has been studied using laser Doppler anemometry. READ MORE
