  1. 6. Black Liquor Scaling Propensity - Experimental Investigation in a Pilot Evaporator

    Författare :Mathias Gourdon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; fouling; sodium sulphate; black liquor; incrustation; scaling; evaporation; falling film; evaporator; encrustation; kraft black liquor;

    Sammanfattning : Scaling in the recovery cycle of kraft pulp mills has long been recognised as a problem, especially in black liquor evaporators. Most problems are connected with the precipitation of sodium salts. LÄS MER

  3. 7. Scaling techniques using CFD and wind tunnel measurements for use in aircraft design

    Författare :Karl Pettersson; Arthur Rizzi; Henrik Alfredsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; wind tunnel; scaling; Reynolds number effect; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel conditions to free flight. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the wind tunnel should be corrected. LÄS MER

  4. 8. The Principle of Scaling of Geographic Space and its Application in Urban Studies

    Författare :Xintao Liu; Bin Jiang; Yifang Ban; Meng Liqiu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographic space; scaling; GIScience; VGI; OSM; heavy-tailed distribution; the head tail division rule; space syntax; nature street; urban sprawl; floating car data; hierarchical spatial structure;

    Sammanfattning : Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems. LÄS MER

  5. 9. Teaching and learning mathematics with integrated small-group discussions. A learning study about scaling geometric figures

    Författare :Jenny Svanteson Wester; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; variation theory; learning study; learning opportunities; small-group discussions; whole-class discussions; whole-class teaching; mathematics; scaling; illusion of linearity;

    Sammanfattning : The aim of this thesis is to contribute to a deeper understanding of the relationship between teaching and student learning in mathematics when small-group discussions are used in teaching. This thesis focuses on student learning of specific subject matter when small group discussions are used in whole-class teaching. LÄS MER
