  1. 1. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts

    University dissertation from Department of Biology, Lund University

    Author : Per Henningsson; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apus apus; aerodynamics; animal flight; kinematics; vortex wake; digital particle image velocimetry; DPIV; common swift; tracking radar; wind tunnel; migration; roosting flight;

    Abstract : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. READ MORE

    Abstract : Popular Abstract in Swedish Fåglars flygförmåga I alla tider har vi fascinerats av fåglars förmåga att flyga, och många försök att förstå och efterlikna dem har gjorts. Kanske den förste som på allvar intresserade sig för mekanismerna bakom fåglars flykt var Leonardo da Vinci som runt år 1500 funderade på hur fåglar alstrar lyftkraft. READ MORE

  3. 3. Experimental and Numerical Studies of Flows Related to the Processes of Atherosclerosis

    University dissertation from Andreas Borg, Division of Fluid Mechanics, Department of Heat and Power Engineering, Ole Römers Väg 1, 221 00 Lund

    Author : Andreas Borg; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Medicinsk teknik; Medical technology; Particle Image Velocimetry; Large eddy simulations; Atherosclerosis; Stenosis; Teknik; Medicine human and vertebrates ; Medicin människa och djur ;

    Abstract : This thesis concerns the prediction of the fluid mechanical conditions in some specific large vessels in the human body. Large vessels are special in the way that the Reynolds number is relatively high and in the case of arteries the flow is pulsatile. READ MORE

  4. 4. Numerical Study of Dispersed Two-phase Flows

    University dissertation from Fluid Mechanics

    Author : Zhilei Wu; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Teknik; Technological sciences; Eulerian Lagrangian model.; Eulerian Eulerian model; Lagrangian Particle Tracking; Large Eddy Simulation; Two-phase flow; Particle Image Velocimetry; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. READ MORE
