  1. 6. Interacting particles and droplets at low Reynolds numbers

    Författare :Lisa Prahl; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; VOS; VOF; Multiphase flow; Interaction; Particles; Droplets; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma;

    Sammanfattning : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. LÄS MER

  3. 7. Stability analysis of channel flow laden with small particles

    Författare :Joy Klinkenberg; Luca Brandt; Cristian Marchioli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; Direct Numerical Simulations; multi-phase flow; heavy particles; light particles; particle-laden;

    Sammanfattning : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. LÄS MER

  4. 8. Disintegration of Lime Mud Particles during the Causticizing Operation

    Författare :Pia Tiljander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CaCO3; Ca OH 2; CaO; lime mud; mixing; particles; slaking; causticizing; disintegration; impeller;

    Sammanfattning : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. LÄS MER

  7. 10. Diskurspartiklar hos ungdomar i mångspråkiga miljöer i Malmö

    Författare :Gudrun Svensson; Lena Ekberg; Catrin Norrby; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; varieties; liksom; typ; du vet; bara; ba; ju; grammaticalization; functional grammar; speech acts; native speakers; information structure; conversational analysis; non-native speakers; contemporary Swedish; adolescents; discourse particles; casual talk; disourse particles; Swedish language; Svenska språket Nordiska språk;

    Sammanfattning : The thesis investigates the use of the discourse particles duvet (you know), ju (as you know), ba(ra) (just), liksom (like), and typ (sort of) among adolescents in contemporary multilingual settings in Malmö. The data is drawn from a corpus of 6 hours’ spontaneous group conversations between female participants. LÄS MER
