Abdelgawad, Marwa (2012-07-16)Homogeneous Charge Compression Ignition (HCCI) Engines hold promises of being the next generation of internal combustion engines due to their ability to produce high thermal efficiencies and low emission levels. HCCI ...
-
Gomez, Patsky O. (2010-01-16)The low NOx burner (LNB) is the most cost effective technology used in coal-fired power plants to reduce NOx. Conventional (unstaged) burners use primary air for transporting particles and swirling secondary air to create ...
-
Breen, Jonathan Robert (2011-10-21)Low temperature combustion (LTC) is an appealing new method of combustion that promises low nitric oxides and soot emissions while maintaining or improving on engine performance. The three main points of this study were ...
-
Lowry, William Baugh (2012-02-14)Natural gas is the primary fuel used in industrial gas turbines for power generation. Hydrocarbon blends of methane, ethane, and propane make up a large portion of natural gas and it has been shown that dimethyl ether ...
-
Peart, Freeman Michael (2009-05-15)There are two coupled objectives for this study of buoyancy-driven turbulence. The first objective is to determine if the development of a Rayleigh-Taylor (RT) mixing layer can be manipulated experimentally by altering the ...
-
Tompkins, Brandon T. (2009-05-15)Biofuels have become very important topics over the past decade due to the rise in crude oil prices, fear of running out of crude oil, and environmental impact of emissions. Biodiesel is a biofuel that is made from plant ...
-
Santos, Bjorn Sanchez (2011-02-22)Increasing fuel prices, stricter government policies, and technological developments made it possible to seek for renewable alternatives, called biofuels, to petroleum fuel. Biodiesel, a biofuel that is produced from ...
-
Rathore, Gurlovleen K. (2011-10-21)Interest in biodiesel has piqued with advent of stringent emissions regulations. Biodiesel is a viable substitute for petroleum diesel because biodiesel produces significantly lower particulate and soot emissions relative ...
-
McLean, James Elliott (2011-10-21)Societal concerns on combustion-based fuel consumption are ever-increasing. With respect to internal combustion engines, this translates to a need to increase brake fuel conversion efficiency (BFCE). Diesel engines are a ...
-
Knight, Bryan Michael (2011-10-21)As global focus shifts towards the health and conservation of the planet, greater importance is placed upon the hazardous emissions of our fossil fuels, as well as their finite supply. These two areas remain intense topics ...
-
Kroupa, Ryan Daniel (2012-07-16)The use of twin-screw pumps for moving fluids is not new technology but its application to wet gas compression (high gas volume fraction [GVF]) is still considered relatively new. There are many advantages for using ...
-
Song, Hoseok (2012-07-16)Biodiesel has been suggested as an alternative fuel to the petroleum diesel fuel. It beneficially reduces regulated emission gases, but increases NOx (nitric oxide and nitrogen dioxide) Thus, the increase in NOx is the ...
-
Hargis, Joshua W. (2015-04-16)For decades Exhaust Gas Recirculation (EGR) has been used to mitigate several issues related to gas turbine operation: CO2 sequestration; NOx formation and emission; and combustor instabilities. EGR increases CO2 concentrations ...
-
Jung, Seunghwan (2012-07-16)The objective of this study is to synthesize nanomaterials by mixing molten salt (alkali nitrate salt eutectics) with inorganic nanoparticles. The thermo-physical properties of the synthesized nanomaterials were characterized ...
-
Rotavera, Brandon Michael (2012-07-16)The focus of the present work is on the empirical characterization and modeling of ignition trends of ternary blends of three distinct hydrocarbon classes, namely a methyl ester (C9H18O2), a linear alkane (n-C9H20), and a ...
-
Esquivel, Jason (2010-01-16)In the wake of global warming and fossil fuel depletion, renewed attention has been paid to shifting away from the use of petroleum based fuels. The world?s energy demand is commencing its dependency on alternative fuels. ...
-
Ravi, Sankaranarayana (2012-02-14)An improved test system for acoustical rating of air-movement devices was installed and evaluated at the Riverside Energy Efficiency Laboratory at Texas A&M University where measurements of sound pressure levels ...
-
Zheng, Junnian (2012-07-16)With the depletion of petroleum based fuels and the corresponding concerns of national energy security issues, natural gas as an alternative fuel in IC engine applications has become an attractive option. Natural gas ...
-
Oak, Sushil Shreekant (Texas A&M University, 2008-10-10)A second law analysis of compression ignition engine was completed using a thermodynamic engine cycle simulation. The major components of availability destruction and transfer for an entire engine cycle were identified and ...
-
Lawand, Vaibhav (2010-07-14)The second law analysis is a powerful tool for assessing the performance of engines and has been employed for few decades now. Turbocharged diesel engines have been explored in much detail with the help of second law ...
