  1. 1. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mhd Osman Bernieh; [2023]
    Keywords : Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Abstract : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. READ MORE

  2. 2. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

  3. 3. Effects of Immiscible Compressor Oil in a Flooded PSHE Evaporator : A Visual Study Approach

    University essay from KTH/Energiteknik

    Author : Joel Blomfelt; [2022]
    Keywords : ;

    Abstract : This paper deals with heat transfer in plate evaporators, with a focus on the effects caused by carried-over compressor oil ending up in the heat exchanger. A common standpoint in literature regarding the effect of immiscible oil contamination, in for example an ammonia PHE evaporator, is that the oil can accumulate as a layer on the plate surface causing an additional thermal conduction resistance.

  4. 4. Brain activity during flow : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Isak Andersson; [2022]
    Keywords : Flow state; neural signatures; functional magnetic resonance imaging; functional near-infrared spectroscopy; electroencephalogram;

    Abstract : The flow state is a subjective experience that most people can relate to. It represents an optimal balance between skills and difficulty and is the state that people often refer to when performing their best, with phrases like: “I was in the zone” or “I was in the bubble”. READ MORE

  5. 5. Burning material behaviour in hypoxic environments: An experimental study examining fire dynamics of composite materials in vitiated conditions

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Robert Bray; [2020]
    Keywords : ORS; Fire engineering; hypoxic; polymers; Technology and Engineering;

    Abstract : The progression of fire safety research has contributed to improving the guiding principles of standardised building design. Research making use of pure materials, once common in homes and workplaces, are less relevant as such materials are no longer as prevalent. READ MORE
