1. 1. Modelling of subgrid-scale stress and passive scalar flux in large eddy simulations of wall bounded turbulent flows

   Författare :Linus Marstorp; Arne V. Johansson; Pierre Comte; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; large-eddy simulation; subgrid-scale model; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : The aim of the thesis is to develop and validate subgrid-scale models that are relevant for large eddy simulations of complex flows including scalar mixing. A stochastic Smagorinsky model with adjustable variance and time scale is developed by adding a stochastic component to the Smagorinsky constant. LÄS MER

3. 2. Development and Application of Pure Rotational CARS for Reactive Flows

   Författare :Alexis Bohlin; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Raman linewidths; gas-phase thermometry; combustion diagnostics; laser spectroscopy techniques; coherent anti-Stokes Raman scattering; molecular spectroscopy; Herman-Wallis factor; Fysicumarkivet A:2012:Bohlin;

   Sammanfattning : The thesis deals with the further development of pure rotational coherent anti-Stokes Raman spectroscopy (RCARS) for improving the capabilities of gas phase thermometry. The main effort has been to make the technique more robust when employed under a wide range of temperatures and operational conditions. LÄS MER
