  1. 21. 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. 22. 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.

  4. 23. Experimental studies of large particles in Newtonian and non-Newtonian fluids

    Författare :Sagar Zade; Luca Brandt; Fredrik Lundell; Ellen Longmire; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.
