Multi-Scale Study of Ember Production and Transport under Multiple Environmental and Fuel Conditions

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...

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...

Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:

Kemling, Gabriel H. and Blunck, David L.

Abstract:

The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...
