  2. 21. Ventilation Performance in Operating Rooms : A Numerical Assessment

    Author : Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

    Abstract : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. READ MORE

  4. 22. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces

    Author : Mehdi Bahador; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Termisk teknik; plasmas; Gaser; Thermal Radiation; Scattering; Heat load; Gases; fluid dynamics; Biomass Furnaces; framdrivningssystem; Motorer; Motors and propulsion systems;

    Abstract : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. READ MORE

  5. 23. Strongly Coupled Performance Prediction for Sailing Yachts based on CFD

    Author : Rickard Lindstrand Levin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Triangle; RANS; Sailing; Velocity Prediction Program; Rigid Body Motion; Wide and Light Yacht; Laser dinghy;

    Abstract : Quantifying performance of sailing yachts can be done in many different ways. Historically the most common way is a static approach where a steady state solution is obtained by solving equilibrium equations in 3 or 4 degrees of freedom. More recently, dynamic methods have appeared. In this thesis a method of the latter kind in proposed. READ MORE

  6. 24. Numerical Simulations of Turbulent Flows at Widely Different Mach Numbers

    Author : Dragos Moroianu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; hydraulics; vacuum technology; Mechanical engineering; plasma; Energy research; Energiforskning; fluiddynamik; plasmas; Gaser; fluid dynamics; Gases; computational fluid dynamics; Acoustic; hydraulik; vakuumteknik; vibrationer; akustik; compressible flow;

    Abstract : The present thesis mainly focuses on the numerical simulation of the turbulent flow field and acoustics developed in different industrial applications. The study covers a large range of Mach numbers, starting from incompressible regimes and ending with a fully compressible flow. READ MORE

  7. 25. Gyrokinetic simulations of turbulent transport in tokamak plasmas

    Author : Andreas Skyman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fusion; TEM; ITG; tokamaks; e-science; Joint European Torus; turbulence; gyrokinetics; plasma physics; impurity transport;

    Abstract : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety. READ MORE
