  4. 2. Numerical Investigations of Turbulent Flow in Water Turbines

    Author : Håkan Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiblock; Parallel; Visualization; Validation; Verification; Turbine; CFD; Francis; Numerical; Kaplan;

    Abstract : This thesis investigates turbulent flow in water turbines, focusing onthe flow in the vicinity of reaction water turbine runners such as theKaplan runner and the Francis runner. The method of investigationis principally numerical although some experimental observations andmeasurements made in the present work and elsewhere are included. READ MORE

  5. 3. EHL investigations using a hybrid technique : an experimental and numerical approach

    Author : Alexei Jolkin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : This licentiate thesis deals with a hybrid experimental and numerical method, the so-called Hybrid Technique, to study film thickness and pressure distribution and to investigate the behaviour and properties of lubricants in highly loaded EHL conjunctions. The Hybrid Technique combines experimental studies and advanced numerical calculations. READ MORE

  6. 4. Numerical instability investigations for thin membranes

    Author : Yang Zhou; Anders Eriksson; Arne Nordmark; Reijo Kouhia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Membrane structures are commonly used in many fields. The studies of these structures are of increasing interest. The projects in this thesis focus on the evaluations of equilibrium states for pressurized membranes under different problem settings, using finite element methods, and the corresponding instability behaviors.

  7. 5. Turbulent jets in confined spaces : application in mixing ventilation: experimental and numerical studies

    Author : Taghi Karimipanah; Mats Sandberg; H. A. Awbi; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; wall jet; impinging jet; free jet; confinement effect; pressure; throw; experimental; numerical; corner; momentum; mixing ventilation;

    Abstract : The basis of mixing ventilation is the airflow supply to the room by means of jets initiatedfrom the ventilation diffusers. To avoid the draught problem, the design of mixing ventilationmakes uses the throw term, which is defined as the distance to the supply air terminal inwhich the jet centreline mean velocity is decreased to a given value.
