1. 1. 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

3. 2. 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.

4. 3. Numerical study of transport phenomena in particle suspensions

   Författare :Mehdi Niazi Ardekani; Luca Brandt; Gianluca Iaccarino; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Suspensions of solid particles in a viscous liquid are of scientific and technological interest in a wide range of applications. Sediment transport in estuaries, blood flow in the human body, pyroclastic flows from volcanos and pulp fibers in papermaking are among the examples. LÄS MER

5. 4. Transport and mixing by finite-size particles in turbulent flows

   Författare :Ali Yousefi; Luca Brandt; Jochen Fröhlich; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning :    Suspensions of solid particles in a viscous fluid are ubiquitous in natural and engineering settings, including sediment transport in river beds, blood flow in the human body, oil products transport in pipelines and pulp fibers in papermaking.    Multiphase flows consisting of finite-size particles is a challenging topic due to multi-way coupling and interactions between the phases.
