  2. 32. Turbulent Shear Flow Experiments: Design of Natural Convection Rig and LDA Measurement in Swirling Jets

    Author : Abolfazl Shiri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Similar Solution; Natural Convection Boundary Layer; Axisymmetric Jet; Laser Doppler Anemometry; Swirl Number;

    Abstract : This work consist of two sections. In the first part, a facility has been installed and modified from an existing rig in order to measure velocity and temperature field of axisymmetric turbulent natural convection boundary layers. With using laser doppler anemometry and cold wire resistance thermometry. READ MORE

  3. 33. Hydrodynamics and heat convection in channels with vibrating walls

    Author : Fredrik Carlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this work a combined analytical and numerical study of the non-linear effects of transverse wall vibrations on fluid flows are presented. Streaming motions and their effect on heat and mass transfer are investigated for a viscous fluid confined in an infinite channel with flexible walls. READ MORE

  4. 34. On the Convective-Scale Predictability of the Atmosphere

    Author : Lisa Bengtsson; Gunilla Svensson; Glenn Shutts; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cumulus convection; cellular automata; model uncertainty; sub-grid scale processes; numerical weather prediction; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : A well-represented description of convection in weather and climate models is essential since convective clouds strongly influence the climate system. Convective processes interact with radiation, redistribute sensible and latent heat and momentum, and impact hydrological processes through precipitation. READ MORE

  5. 35. Prediction of forced convection heat transfer to Lead-Bismuth-Eutectic

    Author : Roman Thiele; Henryk Anglart; Martin Rohde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lead-bismuth-eutectic; Forced convective heat transfer; Turbulence-modeling; GEN-IV reactors;

    Abstract : The goal of this work is to investigate the capabilities of two different commercial codes, OpenFOAM and ANSYS CFX, to predict forced convection heat transfer in low Prandtl number fluids and investigate the sensitivity of these predictions to the type of code and to several input parameters.The goal of the work is accomplished by predicting forced convection heat transfer in two different experimental setups with the codes OpenFOAM and ANSYS CFX using three different turbulence models and varying the input parameters in an extensive sensitivity analysis.
