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

    University dissertation from KTH Royal Institute of Technology

    Author : Sagar Zade; KTH.; KTH.; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Teknisk mekanik; Engineering Mechanics;

    Abstract : 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.

  2. 2. Multiphase flow measurements using ultrasound

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Johan Carlson; Luleå tekniska universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : In process industries such as for example the oil and gas industry, the paper pulp industry, and the mining industry, multiphase flows are common. It is often of interest to measure the mass fractions of the different phases. READ MORE

  3. 3. Fluid dynamics and flow structures of wood fibres suspended in gas flows

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Olof Melander; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two-fluid model; fibres; flocculation; multiphase flow; flow regimes; particle transport; fibre suspensions; Particle Image Velocimetry; Computational Fluid Dynamics; lift force; concentration measurement;

    Abstract : The flow of wood fibres suspended in gas plays a major role in the MDF (Medium Density Fibreboard) production process. Development of machinery in this industry has traditionally been based on experience. Only recently has the use of numerical methods such as CFD (Computational Fluid Dynamics) become an important part of the development process. READ MORE

  4. 4. On the Spray Forming of Metals, the Formation of Porosity and the Heat Evolution during Solidification

    University dissertation from Stockholm : Metallernas gjutning

    Author : José Tinoco; KTH.; [2003]
    Keywords : Thermal analysis; Nodular Cast Iron; Inconel 625; CFD; Flow Assesment; Multiphase Flow; Spray Deposition; Microporosity; Superalloys;

    Abstract : This thesis deals with the heat evolution duringsolidification and its relation to the formation of porosity.It intends to improve the current understanding of theformation of porosity in cast materials with special interestin nodular cast iron and the spray forming process.

  5. 5. Particulate Flows in Aftertreatment Systems

    University dissertation from Stockholm : Metallernas gjutning

    Author : Henrik Ström; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Computational fluid dynamics; Exhaust gas aftertreatment; Particulate matter; Multiphase flow; Particulate flow;

    Abstract : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. READ MORE
