    Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER

  5. 4. Miniaturized fluid system for high-pressure analytics

    Författare :Simon Södergren; Klas Hjort; Sami Franssila; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure; Microfluidics; Thermal regulation; Fluid mechanics; In-situ sensors; High-pressure analytics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

  7. 5. Rapid wetting - influence of surface geometry and fluid properties

    Författare :Susumu Yada; Fredrik Lundell; Shervin Bagheri; Minh Do-Quang; Gustav Amberg; Jacco Snoeijer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting; spreading; surface structures; droplet; contact line; two-phase flow; non-Newtonian flow; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. LÄS MER
