  2. 1. Fluid Power Applications Using Self-Organising Maps in Condition Monitoring

    Author : Anders Zachrison; Jan-Ove Palmberg; Magnus Sethson; Richard Burton; Linköpings universitet; []
    Keywords : 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

  4. 2. 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

  5. 3. Numerical and experimental investigations of fluid-surface interaction

    Author : Aidan Rinehart; Shervin Bagheri; Ugis Lacis; Anna-Lena Ljung; KTH; []
    Keywords : 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

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

    Author : Mattias Ljungqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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

  7. 5. CFD as a tool for analysis of complex geometry : Perspectives on time efficient simulations of interior household appliance components

    Author : Kamal Rezk; Ola Holby; Lars Davidson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Tumble dryer; Fluid mechanics; Design process; Heat exchanger; Comsol MultiPhysics; Volume averaged method; Fluid mechanics; Strömningsmekanik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Throughout recent years, computer based programs has been applied to solve and analyze industrial problems. One of these developed programs is the Computational Fluid Dynamics (CFD) program. The purpose of implementing CFD analysis is to solve complex flow behavior which is not possible with ordinary calculus. READ MORE
