Design Of A Thermal Management System For An Oxy-Methane Direct Power Extraction Combustor, Jad Gerges Aboud
Design Of A Thermal Management System For An Oxy-Methane Direct Power Extraction Combustor, Jad Gerges Aboud
Open Access Theses & Dissertations
The overarching goal of this Thesis is to present the design of a thermal management system for an oxy-methane direct power extraction combustor. The design is initiated by performing a 2D analysis on the combustor geometry and then using these results in a 3D model. This is done by using results for heat transfer coefficient and temperatures found from the 2D simulation and importing these to the 3D model. The approach used here couples the combustion process, heat transfer through the chamber wall, and fluid flow behaviors in order to observe the thermal characteristics of the combustor during operation. This …
Combustion Of Novel Thermite Mixtures For Iodine Generation, Sergio Emanuel Guerrero
Combustion Of Novel Thermite Mixtures For Iodine Generation, Sergio Emanuel Guerrero
Open Access Theses & Dissertations
Halogen-containing reactive materials could be used for mitigating the spread of hazardous, active biological microorganisms aerosolized as a result of explosion. The present work exhibits experimental results on the combustion of mechanically alloyed aluminum-iodine (Al-I2) powder mixed with Fe2O3, CuO, MoO3, Bi2O3, and I2O5. Wet mixing was used to prepare the samples, which were then compacted into pellets and ignited with a CO2 laser. A chamber was designed and built to accommodate for combustion and collection of products, and the available laser ignition setup was modified to enable combustion experiments with rapidly burning gas-generating mixtures. High-speed video recording was used …
Characterization Of High Intensity Turbulent Flows Through Time Resolved Particle Image Velocimetry In A Backward Facing Step Combustor, Martin De La Torre
Characterization Of High Intensity Turbulent Flows Through Time Resolved Particle Image Velocimetry In A Backward Facing Step Combustor, Martin De La Torre
Open Access Theses & Dissertations
The fundamental understanding of turbulent premixed combustion has taken place as one of the major research topics of interest in industry thanks to advancements in kHz level laser diagnostics such as in Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF). Because of said advancements in this technology researchers and the scientific community are now able to expand their understanding of flame studies at high turbulence conditions to acquire a better understanding, and improve models used in turbine design, scram/ram jets, rocket engines, and emissions control. This surge of new technologies has made this topic a high priority one …
Investigation Of Ti-6al-4v Alloy Response To Atmospheric Re-Entry Exposure, Jessica Lynn Buckner
Investigation Of Ti-6al-4v Alloy Response To Atmospheric Re-Entry Exposure, Jessica Lynn Buckner
Open Access Theses & Dissertations
Ti-6Al-4V is a widely used aerospace alloy for its high strength-to-weight ratio and high operating temperature properties. Despite widespread use, titanium and its alloys have been shown to ignite in oxygen and nitrogen rich test streams. The reactivity of titanium is attributed to the high solubility for oxygen that increases with temperature, accelerating the oxidation rate and resulting in a combustion reaction. When introduced to the monatomic oxygen rich and high enthalpy re-entry environment, Ti-6Al-4V X-link components from the space shuttle Columbia exhibited accelerated oxidation and combustion behavior. Ti-6Al-4V metal plates tested in the simulated re-entry environment of an arc-jet …
