  1. 1. Approaches for improving the rheological characterization of fermented dairy products

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Abdulrahman Muhammad; [2020]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.

  3. 2. Extensional Instability in Complex Fluids: A Computational Study

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Muhammed Abdulrazaq; [2020]
    Keywords : Complex Fluids; Computational Rheology; Elastoviscoplastic Fluids; Instability.; Komplexa vätskor; Beräkningsreologi; Elastoviskoplastiska vätskor; Instabilitet.;

    Abstract : In this study, instability and failure in complex fluids (Elastoviscoplastic fluids) is explored using the classic Considère (F˙ < 0) and stress curvature (σ¨ < 0) criteria. Employing the Saramito model, numerical simulation of the extensional protocol on non-Newtonian fluids is carried out. READ MORE

  4. 3. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  5. 4. An investigation of boundary layer growth in pulp suspensions over a flat plate

    University essay from Institutionen för fysik

    Author : Emelie Wibron; [2013]
    Keywords : ;

    Abstract : The pulp and paper industry consumes high amount of energy when producing paper. Large flows of pulp suspensions are handled during the process. There is still a lack of knowledge of the flow and fluid properties of pulp suspensions which is important in the design and operation of more efficient process equip- ment. READ MORE
