Ignition of Fuel Beds by Firebrands

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...

Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

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...

The Global Consumption Speeds of Premixed Large-Hydrocarbon Fuel/Air Turbulent Bunsen Flames

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...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:

Caplan, Daniel L.

Abstract:

In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...
