Schweizer, Christian M. (2023-08-04)Dust explosions threaten people, assets, and the environment across a wide range of industries. To identify hazards and manage risks, dust materials must be tested with standard methods and equipment like the MIKE3 minimum ...
-
Tompkins, Brandon T (2015-08-12)The first stage of ignition in saturated hydrocarbon fuels (in diesel combustion) is characterized as low temperature heat release (LTHR) or cool flame combustion. LTHR takes place as a series of isomerization reactions ...
-
Cornejo, Juan Antonio (2020-01-08)This investigation characterized early frost formation by quantifying the velocity of the aggregate freezing front and examining the underlying factors that have a direct effect on it. The experiments were carried out under ...
-
Griffin, Aaron A (2015-07-30)Naturally, there are complex interactions among internal combustion engine parameters such as in-cylinder pressure, emissions, speed, and load. These basic relationships are studied in a naturally aspirated, spark-ignited, ...
-
Gill, Matthew Thomas (2016-05-03)Multiple vital industries, especially those in the energy sector, are vulnerable to unexpected detonation events. Extremely destructive and difficult to predict, the processes by which they are formed and the limits over ...
-
Xue, Xingyu 1985- (2012-11-15)A detailed multi-zone thermodynamic simulation has been developed for the direct-injection (DI) diesel engine combustion process. For the purpose of predicting heterogeneous type combustion systems, the model explores the ...
-
McKeathen, Benjamin Jack (2018-03-22)Diesel engine combustion is heavily impacted by the chemical and physical properties of the fuel being used. Fuel composition plays a role in the in-cylinder behavior of the fuel and the emissions produced during combustion. ...
-
Li, Tingting (2017-07-18)Reciprocating engines are pervasively used in the transportation industry. The transportation industry is centered on achieving two important but often conflicting goals: 1) improved energy efficiency and 2) decreased ...
-
Cooper, Sean Patrick (2022-12-08)Ignition of the lubricating fluid in a mechanical system is a highly undesirable and unsafe condition that can arise from the elevated temperatures and pressure to which the lubricant is subjected. It is therefore important ...
-
Brown, Jeffrey Louis (2017-05-05)In the midst of a controversial time in the energy industry, it is hard to deny the fact that petroleum-based combustion will be a mainstay for many years to come. In light of this reality, it is the task of the engineering ...
-
Bajwa, Abdullah Umair (2020-09-29)Gas exchange processes in two-stroke internal combustion engines, commonly referred to as scavenging, are responsible for removing exhaust gases from the combustion chamber and preparing the fuel-oxidizer mixture that ...
-
Ozaydin, Mehmet Fevzi (2016-10-24)Integrated fabrication techniques in order to develop novel multi-functional hybrid materials for potential applications in energy conversion and sustainability were investigated. There are three major areas of investigation ...
-
Aul, Christopher J (2013-05-02)The hydroxyl (OH) radical is a common intermediate species in any hydrogen- or hydrocarbon-based flame. Investigating OH at elevated temperatures and pressures is not a trivial task, and many considerations must be made ...
-
Thomas, James C (2018-12-04)Hybrid rockets have distinct advantages over their pure solid or liquid propellant counterparts, but their widespread application has been hindered by characteristically low regression rates and combustion efficiencies. A ...
-
Assuncao, Felipe Leite (2016-08-02)This thesis presents a 2D numerical analysis of a cross flow compact energy recovery ventilator (HRV) with staggered baffle channels, using finite difference iterative method. The model was developed by discretization of ...
-
Linker, Taylor F (2019-11-14)The ultimate goal of this work is to aid in the improvement of emissions control methods for compressor engines used in the natural gas transmission pipeline industry. The work presented here contributes to that larger ...
-
Rodriguez, Oscar (2012-12-06)RELAP5-3D has been coupled with both DAKOTA and STAR-CCM+ in order to expand the capability of the thermal-hydraulic code and facilitate complex studies of desired systems. In the first study, RELAP5-3D was coupled with ...
-
Fieseler, Kelsey Danielle (2018-08-05)The overall goal of this project is to improve upon existing engine control strategies used for large bore, lean-burn, natural gas engines in order to increase efficiency and maintain emissions compliance during variable ...
-
Sun, Jiafeng (2014-08-05)Diesel/gasoline dual-fuel combustion uses both gasoline and diesel fuel in diesel engines to exploit their different reactivities. This operation combines the advantages of diesel fuel and gasoline while avoiding their ...
-
Thomassie, Rachal Elizabeth (2019-04-04)Mechanical engineering has long been a prominent and popular field of study, preparing graduates for a variety of jobs and careers. This discipline is often described as “broad”; however, one topic that is lacking in ...
