A turbulent diffusion flame that is typically used in a thermal spray coating system was analyzed in this study, as part of a diagnostic and development program undertaken by a research group at Queen’s University. Contributions made by this researcher were to numerically and experimentally investigate velocity and turbulent fields of the gaseous phase of the jet. Numerical and experimental analyses have been further developed upon previous research, with improved numerical methods and advanced experimental instrumentation. Numerous numerical simulations were performed in both two dimensional axisymmetric and three dimensional wedge geometries, while testing the dependence of the final solution on various physical models. Numerical analyses revealed the requirement for simulating this problem in three dimensions and improved turbulence modeling to account for relatively high levels of anisotropy. Velocity and turbulent measurements of non-reacting and combusting jets were made with a laser Doppler anemometer to validate numerical models. Excellent agreement was found between predicted and measured velocity and turbulent quantities for cold flow cases. However, numerical predictions did not agree quite as well with experiments of the flame due to limitations in modeling techniques and flow tracking abilities of tracer particles used in experimentation. / Thesis (Master, Mechanical and Materials Engineering) -- Queen's University, 2007-09-28 13:05:54.365
