The sources of aerosol particle formation studied are the following: 1. production of primary aerosol particles in the high Arctic region during summers 2. READ MORE

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

    University dissertation from Food Engineering, Technology and Nutrition

    Author : Fredrik Innings; Lund University.; Lunds universitet.; [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 : The overall aim of this project was to investigate the drop break-up process in milk homogenisers. This was done by measurements and calculations of the flow fields in the gap region and by visualisation of drops being broken up. To make visualisation and measurements possible, two scale models of a homogeniser gap were developed. READ MORE

  3. 3. Turbulence-droplet interaction modelled by One-Dimensional-Turbulence

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Marco Fistler; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; One-Dimensional-Turbulence ODT ; Multiphase Flow; Turbulence; Droplets;

    Abstract : A stochastic model to study droplet/particle influence on the gas phase using the One-Dimensional-Turbulence model (ODT) is evaluated. To address one of the major problems for multiphase flow simulations, namely computational costs, the dimension-reduced model is used with the goal of predicting certain classes of these flows more efficiently.

    Abstract : This thesis concerns nozzles and their impact on droplet formation and droplet flight in a continuous ink jet printer. Methods are suggested to characterise droplet formation and droplet flight stability (D.F.S. READ MORE

  5. 5. Properties of Multifunctional Oxide Thin Films Despostied by Ink-jet Printing

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mei Fang; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ink-jet printing; oixde; thin film; ink; suspension; dye sensitized solar cell; functional properties; magnetism; diluted magnetic semiconductors;

    Abstract : Ink-jet printing offers an ideal answer to the emerging trends and demands of depositing at ambient temperatures picoliter droplets of oxide solutions into functional thin films and device components with a high degree of pixel precision. It is a direct single-step mask-free patterning technique that enables multi-layer and 3D patterning. READ MORE
