  1. 16. Rock mass response during high pressure grouting

    Författare :Rikard Gothäll; Håkan Stille; Johan Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : The sealing of hard jointed rock by grouting involves several complicated mechanical systems. The result is a complex coupled system of hydro- logical and mechanical precesses. In order to determine the higher order effects of the resulting system the fracture deformations must be assessed. LÄS MER

  5. 19. Drop Break-up in High-Pressure Homogenisers

    Författare :Fredrik Innings; Livsmedelsteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 20. Hygro-Elastic Deformation of High Pressure Laminates. A Macroscopic Analysis. Theoretical Modelling and Measurements

    Författare :Bijan Adl-Zarrabi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; expansion; elastic deformation; moisture transport; orthotropic; high pressure laminate;

    Sammanfattning : Deformation due to environmental changes in moisture arises in many engineering problems of practical interest. The purpose of this work is to develop a theoretical model for the determination of moisture induced deformations in thin plates made of High Pressure Laminates. LÄS MER
