  2. 1. Numerical and experimental investigations of fluid-surface interaction

    Author : Aidan Rinehart; Shervin Bagheri; Ugis Lacis; Anna-Lena Ljung; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; porous media; Brinkman equation; surface; Engineering Mechanics; Teknisk mekanik;

    Abstract :  Fluid-structure interactions play a central role in an overwhelming number of physical phenomena. All fluid dynamic students are familiar with the common assumption of a "smooth boundary". While this assumption often is enough to provide a high level understanding of the dynamics and physics at hand in practice this is not true. READ MORE

  4. 2. Fluid and Solid Particle Dynamics in Stirred Vessels

    Author : Mattias Ljungqvist; Chalmers University of Technology; []
    Keywords : mixing time; pitched blade turbine; impeller modelling; stirred vessels; computational fluid dynamics; multi-fluid model; suspension of solids; phase-Doppler anemometry; laser Doppler anemometry; closed vessels;

    Abstract : The present thesis deals with the fluid dynamics of stirred vessels and particularly those that are to be used in conjunction with solids suspensions. Stirred vessels are very common in the process industry and large amounts of energy can be saved by optimising their operation. READ MORE

  5. 3. Fluid Power Applications Using Self-Organising Maps in Condition Monitoring

    Author : Anders Zachrison; Jan-Ove Palmberg; Magnus Sethson; Richard Burton; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; pneumatic; self-organizing maps; condition monitoring; Signal processing; Signalbehandling;

    Abstract : Condition monitoring of systems and detection of changes in the systems are of significant importance for an automated system, whether it is for production, transport, amusement, or any other application. Although condition monitoring is already widely used in machinery, the need for it is growing, especially as systems become increasingly autonomous and self-contained. READ MORE

  6. 4. Multiobjective optimization in engineering design : applications to fluid power systems

    Author : Johan Andersson; Sören Andersson; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis focuses on how to improve design and development of complex engineering systems by employing simulation and optimization techniques. Within the thesis, methods are developed and applied to systems that combine mechanical, hydraulical and electrical subsystems, so-called multi-domain systems. READ MORE

  7. 5. Particle image velocimetry in practice

    Author : Torbjörn Green; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased. READ MORE
