  1. 1. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Naser Hamedi; Lunds universitet.; Lund University.; [2016]
    Nyckelord :Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

    Sammanfattning : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. LÄS MER

  2. 2. Compression moulding of SMC experiments and simulation

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jimmy Olsson; Luleå tekniska universitet.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER

  3. 3. Simulations of turbulent boundary layers with suction and pressure gradients

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Alexandra Bobke; KTH.; KTH.; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layers; near-wall turbulence; history effects; asymptotic suction boundary layers; large-eddy simulation;

    Sammanfattning : The focus of the present licentiate thesis is on the effect of suction and pressure gradients on turbulent boundary-layer flows, which are investigated separately through performing numerical simulations.The first part aims at assessing history and development effects on adverse pressure-gradient (APG) turbulent boundary layers (TBL).

    Sammanfattning : Experiments have been carried out to measure traction, antiwear and rheological properties of water-based hydraulic fluids. Four types of fluids have been examined, emulsions, micro-emulsions, synthetic solutions and water-glycols. LÄS MER

  5. 5. Hydrodynamic control of retention in heterogeneous aquifers and fractured rock

    Detta är en avhandling från Stockholm : KTH

    Författare :Hua Cheng; KTH.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer; Fracture; groundwater; First-order solution; Monte-Carlo simulation; Nu-clear waste; Heterogeneity; Retention processes; Matrix diffusion; Prediction; Evaluation; Travel time; Flow rate; ; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Sammanfattning : In this thesis, fluid flow and solute transport in heterogeneous aquifers and particularly in frac-tured rock have been investigated using Lagrangian Stochastic Advective-Reaction (LaSAR) framework. The heterogeneity of the aquifer structure or fracture configuration, as well as the various reaction/retention processes have been considered in the modelling approach. LÄS MER
