Creator:: Teope, Kaz I.
Abstract:: The operation of gas turbine engines depends on the reliable ignition of fuel/air mixtures. Gas turbine engines are commonly used as commercial and military aviation power plants. However, consistent ignition within gas turbine engines is still a problem, especially for more challenging operating conditions such as emergency operations. This work...
Resource Type:: Dissertation

Creator:: Smucker, Benjamin
Abstract:: Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...
Resource Type:: Dissertation

Creator:: Fillo, Aaron Jesse
Abstract:: Large-hydrocarbon fuels are used for ground and air transportation because of their high energy-density and will be for the foreseeable future. However, combustion of large-hydrocarbon fuels in a turbulent environment is poorly understood and difficult to predict. The turbulent flame speed, which is the velocity at which a flame front...

Creator:: Okhovat, Sebastian
Abstract:: Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

Creator:: Ross, Andrew H.
Abstract:: Smoldering can play a dangerous role in the ignition and spread of wildfires. Naturally occurring fuels consist of multiple layers of organic materials with varying particle sizes due to differences in decomposition stages with fuel depth, yet the influence of particle size on burning behavior is poorly understood. Previous research...

Creator:: Hudson, Tyler R.
Abstract:: Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...

Creator:: Bean, Derek R.
Abstract:: The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

Creator:: Fazeli, Hamid
Abstract:: Wildland fire refers to an unpredictable and uncontrollable fire that happens in wildland areas. Regardless of the beneficial impacts of wildland fires on ecosystems, the destructive impacts of wildfires on air quality, economy, public health, etc. are considerable. An essential goal in the fire community is that the wildland fires...
