(2017-04-19)Recent interest in the replacement of hydrazine as a liquid monopropellant has focused on the use of hydroxylammonium nitrate (HAN)-based monopropellants. HAN-based monopropellants offer benefits of improved performance ...
-
(2023-07-09)The major challenge in designing oxy-fuel combustors in supercritical power generation cycles is the lack of fundamental understanding of the combustion process at high pressures exceeding the critical point of the fuel ...
-
(2015-08-19)To simulate the combustion of a flame, or any reacting fluid flow, it is necessary to incorporate a reaction mechanism which describes the incremental steps and associated rates leading from reactant species to products. ...
-
(2020-08-27)A new shock-tube facility for the study of gas- and condensed-phase measurements has been developed for the investigation of various hydrocarbon species. At present, the shock-tube facility is intended for studying combustion ...
-
(2019-05-28)A direct numerical simulation (DNS) of a propagating H2-air flame in a semi-confined geometry is performed and analyzed. Simulation setup imitates the flow conditions in the Turbulent Shock Tube (TST) facility developed ...
-
(Texas A&M University, 2004-11-15)The objectives of this study were to 1) determine the effects of cycle-to-cycle variations (ccv) on nitric oxide (NO) emissions, and 2) determine if the consideration of ccv affects the average NO emission as compared to ...
-
(2015-11-05)Aqueous solutions of hydroxylammonium nitrate (HAN) are promising as possible replacements for hydrazine as liquid rocket propellants. HAN-based propellants offer lower toxicity, higher density, and possibly higher specific ...
-
(2013-12-02)The existence of flammable aerosols creates fire and explosion hazards in the process industry. Due to the operation condition of high pressure circumstances, heat transfer fluids tend to form aerosols when accidental ...
-
(Texas A&M University, 2005-02-17)Computational Fluid Dynamics (CFD) is a field that is constantly advancing. Its advances in terms of capabilities are a result of new theories, faster computers, and new numerical methods. In this thesis, advances in the ...
-
(2017-05-08)The objective of this work is to characterize emissions from solid propellants using a non-intrusive optical diagnostic method, primarily focusing on the release of the metallic species of aluminum (Al), copper (Cu), lead ...
-
(Texas A&M University, 2006-04-12)The quasi-steady, spherically symmetric combustion of multicomponent isolated fuel droplets has been modeled using modified Shvab-Zeldovich variable mechanism. Newly developed modified Shvab-Zeldovich equations have been ...
-
(2019-04-03)The work performed in this research is aimed at developing two repeatable methods for imaging spherically expanding flames operated in a constant volume flame vessel. The first, passive diagnostic method imaged the ...

-
(2017-05-31)Computational fluid dynamics (CFD) is now a ubiquitous computational tool for engine design and analysis. It is often necessary to provide well-known initial cycle conditions to commence the CFD computations. Such initial ...
-
(Texas A&M University, 2007-04-25)Growing rates of manure produced from large dairies have increased concern for the environmental quality of nearby streams and watersheds. Typically the manure from the freestalls on these dairies is flushed with water to ...
-
(2015-08-07)An ongoing project for the construction of a high-pressure, high-temperature turbulent flame speed vessel is furthered in this study. Prior to this work, a laminar flame bomb apparatus was repurposed as a turbulent flame ...
