  1. 1. Colloidal carrier substances : Properties and impact on trace metal distribution in natural waters

    Författare :Anna Ledin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Colloidal (0,45 J.Im) are important constituents in the aquatic environment, due to their impact on the mobility and bioavailability of associated components (e.g. metals). LÄS MER

  3. 2. Particle-laden Turbulent Wall-bounded Flows in Moderately Complex Geometries

    Författare :Azad Noorani; Philipp Schlatter; Helge Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; complex geometry; particle; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Wall-bounded turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the carrier and the particulate phase is elevated to a higher level when introducing geometrical complexities such as curved walls. LÄS MER

  4. 3. Mechanisms of adhesive mixing for drug particle inhalation (Numerical investigation of the interplay between formulation variables)

    Författare :Mohammadreza Tamadondar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Agglomerate; Carrier Particle; Adhesive mixing; Dispersion; DPI-formulation;

    Sammanfattning : Formulation of therapeutic dry powders for lung drug delivery via inhalation is done via adhesive mixing. In this process, micron-sized active pharmaceutical ingredient particles are blended with relatively coarse carrier particles until stable adhesive units of carrier and drug particles are formed.

  5. 4. Laminar and turbulent particle laden flows : a numerical and experimental study

    Författare :Seyed Hamid Tabaeikazerooni; Luca Brandt; Jeanette Hussong; Raffaella Ocone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspension flow; inertial effect; turbulent duct flow; finite-size particles; Immersed Boundary Method IBM ; Astigmatism Particle Tracking Velocimetry APTV ; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Particle laden flows are widespread in nature and in industrial applications. Dust storms, geophysical flows, pharmaceutical processes, fluidized beds and blood flow are only a few examples. Both global and local properties of a particle laden flow may alter significantly in comparison to the corresponding single phase flow. LÄS MER

  7. 5. Numerical study of particle suspensions in Newtonian and non-Newtonian fluids

    Författare :Dhiya Alghalibi; Luca Brandt; Metin Muradoglu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inertial suspensions; rheology; non-Newtonian fluids; visco-elastic; sedimentation; deformable particle; hyper-elastic.; tröghetsbehäftad suspension; reologi; icke-Newtonska fluider; vis- koelastik; sedimentering; deformerbara partiklar; hyperelastik; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Solid or deformable particles suspended in a viscous fluid are of scientific and technological interest in a broad range of applications. Pyroclastic flows from volcanoes, sedimentation flows in river bed, food industries, oil-well drilling, as well as blood flow in the human body and the motion of suspended micro-organisms in water (like plankton) are among the possible examples.
