  1. 1. The Influence of Water Vapour on the Oxidation Behaviour of High-temperature Materials Microstructure investigation using analytical electron microscopy

    Författare :Jun Eu Tang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEM; EDS; SEM; oxidation; microstructure; water vapour; stainless steel; vaporisation; FIB;

    Sammanfattning : This thesis covers the analytical electron microscopy work carried out on samples exposed to high-temperature oxidation in O2 atmospheres with the intention of investigating the effect of oxygen and water vapour. SEM/EDS, TEM/EDS and diffraction techniques, complemented by FIB precision milling, were employed to characterise the formed oxide scales as well as the material directly under the scale in order to understand the mechanisms that influence the corrosion process.

  5. 4. LES stochastic modelling of cavitation with its applications in OpenFOAM

    Författare :Boxiong Chen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cavitation; Rayleigh-Plesset Model; Simulation; OpenFOAM; Volume of Fluid Method; Modeling;

    Sammanfattning : Cavitation is a vaporisation process that commonly happens in high pressure injectornozzles nowadays. It has been shown by previous studies that cavitationhas a significant influence on the subsequent atomization process, the qualityof which would in turn heavily affect the quality of combustion.

  7. 5. Application of Numerical Aerothermal Models on Jet Engine Combustors

    Författare :Stefan Olovsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of numerical simulations with combustion for predicting the flow field in a gas turbine combustor or afterburner may reduce the required time in the development process. To investigate the performance of numerical simulation codes some different combustor geometries was studied. LÄS MER
