  4. 7. Transitional flow in ordered porous media

    Author : Tobias Forslund; Staffan Lundström; Sofia Larsson; Gunnar Hellström; Krishna Pillai; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Porous media; Lattice Boltzmann Method; GPU Programming; Tomographic PIV; Laser Doppler Velocimetry; Strömningslära; Fluid Mechanics;

    Abstract : Porous media, here defined as any permeable structure allowing a fluid to flow through, are relevant to a multitude of engineering applications and natural processes. The observed macroscopic properties of the porous media such as mixing, heat transfer and apparent permeability are properties which are affected by the flow and especially the type of flow, or flow region.

  5. 8. Transitional and turbulent fibre suspension flows

    Author : Mathias Kvick; Fredrik Lundell; Daniel Söderberg; Lisa Prahl Wittberg; Björn Hof; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; fibre suspension; turbulence; laminar-turbulent transition; image analysis; hydrodynamic stability; cellulose nanofibrils.; Engineering Mechanics; Teknisk mekanik;

    Abstract : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. READ MORE

  6. 9. Modelling of stably-stratified, convective and transitional atmospheric boundary layers using the explicit algebraic Reynolds-stress model

    Author : Velibor Zeli; Gert Brethouwer; Arne V. Johansson; Stefan Wallin; Bert Holtslag; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric turbulence; convective atmosphere; Reynolds-stress model; stably-stratified atmosphere; transitional atmosphere; Engineering Mechanics; Teknisk mekanik;

    Abstract : The atmospheric boundary layer (ABL) is in continuous turbulent motion. The heating and cooling of the Earth’s surface drives mechanic and thermodynamic processes in the ABL through enhancing and damping of atmospheric turbulence. The surface forcing has a profound effect on the diurnal cycle of temperature,wind and related variables in the ABL. READ MORE

  7. 10. Child nutrition in rural Nicaragua : Population-based studies in a transitional society

    Author : Mariela Contreras; Eva-Charlotte Ekström; Anders Hjern; Christel Larsson; Uppsala universitet; []
    Keywords : autonomy; education; feeding practices; food security; nutritional status; social support; Nutrition; Nutrition;

    Abstract : Emerging favourable as well as unfavourable nutrition patterns are observed in societies undergoing rapid social and economic change. The aim of this thesis is to analyse the associations between household and maternal resources and infant and young child feeding habits and nutritional status in rural Nicaragua, a low-income transitional society.
