Abstract
This dissertation presents advanced measurement science that ultimately supports the design, development, and characterization of next-generation energy systems. Part I presents a mathematical framework and approach for measuring the composition of complex, reacting gaseous mixtures with multi-wavelength laser-absorption spectroscopy. Suites of laser systems were interfaced with shock tubes to measure the composition of mixtures during the pyrolysis of a single-component fuel (1-butene), alternative (carbon-neutral) jet fuel mixtures, and traditional jet fuels. These methods were established to help determine the time-dependent composition of complex high-temperature chemistry. With the framework of Part I in place, Part II presents work that increases the number of laser wavelengths used by a factor of 10, while reducing the hardware needed to acquire this extra information. The second part of this thesis adopts an emerging technology, known as dual-comb spectroscopy, for use in high-temperature reaction kinetic studies. This approach provides ultra-fast broadband absorption data used in a variety of conditions in the different chapters of Part II. Taken together, the two parts of this thesis provide a framework for characterizing complex and reacting high-temperature gas mixtures and introduce advanced tools that push the boundary of measurement capability.
