  1. 1. Numerical and experimental study of turbulent drop breakup in high­-pressure homogenizers

    Author : Peyman Olad; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure homogenizer HPH ; Turbulent drop breakup; Computational fluid dynamics CFD ; Direct numerical simulations DNS ; Experiments;

    Abstract : Emulsification is the process of making stable mixture of two or more immiscible substances (typically oil and water). The product of this process, the emulsion, is found in various applications and industries such as food (milk and other dairy products, non-dairy alternatives, mayonnaise, salad dressing), cosmetics and pharmaceuticals (creams, lotions, intravenous medications), chemical (paints, cleaning products), etc. READ MORE

  2. 2. Scenarios of drop deformation and breakup in sprays

    Author : Tímea Kékesi; Lisa Prahl Wittberg; Gustav Amberg; Mireia Altimira; Stéphane Zaleski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : Sprays are used in a wide range of engineering applications, in the food and pharmaceutical industry in order to produce certain materials in the desired powder-form, or in internal combustion engines where liquid fuel is injected and atomized in order to obtain the required air/fuel mixture. The optimization of such processes requires the detailed understanding of the breakup of liquid structures. READ MORE

  3. 3. Microstructure of spray dried particles at different scales of drying

    Author : Marine Nuzzo; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

    Abstract : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. READ MORE

  4. 4. Simulations of cavitation - from the large vapour structures to the small bubble dynamics

    Author : Aurélia Vallier; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Very few people around us know the meaning of the word cavitation, except from those who saw the movie "The Hunt for Red October" and can relate cavitation to Sean Connery in a submarine. Some of them know that it corresponds to the formation of bubbles, due to a pressure drop, and causes erosion and noise. However, cavitation is much more complex. READ MORE

  5. 5. Phenomenological and mechanistic modeling of melt-structure-water interactions in a light water reactor (LWR) severe accident

    Author : Anh Bui Viet; KTH; []
    Keywords : ;

    Abstract : Severe accidents in light water reactors have been the fotalpoint of much research, performed in the last two decades,aimed at understarrding the inherent physical phenomena and toevaluate proposed accident management schemes for mitigatingthe consequences of such accidents. Severe accident progressionand consequences, av the reactor core overheats and melts, areintimately related to the interactions of the melt with coolant(water) and structures. READ MORE
