  1. 1. Drop Break-up in High-Pressure Homogenisers

    University dissertation from Food Engineering, Technology and Nutrition

    Author : Fredrik Innings; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; plasma; fluiddynamik; Gaser; plasmas; fluid dynamics; POD; Gases; PIV; Eddy; Flow; Jet; Milk; Break-up; Emulsion; Drop; Homogeniser;

    Abstract : Popular Abstract in Swedish Den här avhandlingen behandlar hur fettdroppar i mjölk slås sönder i en mjölkhomogenisator. Mekanismerna bakom sönderslagningen har analyserats genom uppmätning av flödesfältet i spalten samt genom att fotografera dropparna, när de slås sönder. READ MORE

  2. 2. Air flows in building components

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Johnny Kronvall; [1980]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air flow; air movement; building component; fluctuating pressure; leakage; pressurization; permeability; porosity; surface roughness; entrance; bend; exit pressure loss; pressure drop; infiltration; convection;

    Abstract : This work deals with different aspects of air movements in building components . The investigation shows to what degree the concept of fluid mechanics can be applied to problems concerning air flows in building Components. The applicable parts of fluid mechanics are presented as thoroughly as possible. READ MORE

  3. 3. Flow Boiling Heat Transfer and Pressure Drop. Experiments and Model Development for Complex Geometries

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Sven Wellsandt; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pressure drop; zeotropic mixtures; heat transfer; herringbone microfin; dimple plate; modelling; evaporation; flow boiling; experiments;

    Abstract : Two very different evaporator geometries, a dimple plate and a herringbone microfin tube, have been studied. Heat transfer and pressure drop for both pure refrigerants and refrigerant mixtures have been determined experimentally. READ MORE

  4. 4. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes

    University dissertation from Stockholm : KTH

    Author : Wahib Owhaib; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minichannel; microchannel; heat transfer; pressure drop; single-phase; two-phase; flow boiling; flow visualization; dry out; bubble behavior; flow pattern.; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Abstract : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. READ MORE

  5. 5. Flow boiling heat transfer, pressure drop and dryout characteristics of low GWP refrigerants in a vertical mini-channel

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Zahid Anwar; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mini micro-channels; R1234yf; R152a; R600a; R134a; Boiling heat transfer; Pressure drop; Dryout; Correlation;

    Abstract : Two-phase heat transfer in mini/micro-channels is capable of meeting the high cooling demands of modern high heat flux applications. The phase change process ensures better temperature uniformity and control for local hot spots. Furthermore, these compact channels could be helpful in reducing the required charge and material inventories. READ MORE
