  1. 1. Rheological Behaviour of Biopolymer Gels in Relation to Structure

    Author : Mats Stading; Chalmers University of Technology; []
    Keywords : particulate gels; fine-stranded gels; mixed gels; biopolymer gels; inhomogeneous gels; rheological properties; rheological behaviour;

    Abstract : The rheological behaviour of biopolymer gels with different network structures was studied to elucidate how the structure of the gel influences its rheological properties. Non-destructive viscoelastic measurements and fracture techniques were used. READ MORE

  3. 3. Fibre orientation and rheological behaviour in compression moulding

    Author : Fredrik C Vahlund; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Compression moulding is a common manufacturing process for composite materials. In order to better predict the processing and performance of components, simulation tools are becoming more important. In this thesis the behaviour of the compression moulding raw material has been studied to provide a platform for better simulations. READ MORE

  4. 4. Wheat Flour Dough-Rheological and Structural Aspects

    Author : Helena Larsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; starch gel; gluten; water distribution; lipids; starch granule surface; starch content; mixing; ultracentrifugation; structure; rheological measurements; wheat flour dough; phase separation; ethyl hydroxyethyl cellulose; Food and drink technology; Livsmedelsteknik;

    Abstract : The thesis presents a rheological study on wheat flour dough, in relation to the structural influence of the different dough constituents, added components and mixing time. Rheological investigations have been focused on measurements at small deformations, including dynamic oscillation and stress relaxation, although complementing measurements have been performed in large deformation viscosity experiments.

  5. 5. Structure-Control of the Rheological Behaviour of Particulate Gels

    Author : Camilla Olsson; Chalmers University of Technology; []
    Keywords : structure formation; potato amylopectin; structure deformation; rheology; particulate gels; image analysis; beta-lactoglobulin; fracture mechanics; microstructure;

    Abstract : The focus of this thesis is the relation between the rheological and structural properties of mixed particulate gels, based on β-lactoglobulin, determined under both dynamic and static conditions. Rheological characteristics were recorded during formation of the gels, on set gels and during deformation and fracture of the gels, using viscoelastic measurements in shear and in compression and fracture mechanics in tension.
