Risk Assessment of Transmission Lines Against Grid-ignited Wildfires [PDF]

arXiv
Wildfires ignited by the power lines have become increasingly common over the past decade. Enhancing the operational and financial resilience of power grids against wildfires involves a multifaceted approach. Key proactive measures include meticulous vegetation management, strategic grid hardening such as infrastructure undergrounding, preemptive de ...

An Investment Prioritization Model for Wildfire Risk Mitigation Through Power Line Undergrounding [PDF]

arXiv
Grid-ignited wildfires are one of the most destructive catastrophic events, profoundly affecting the built and natural environments. Burying power lines is an effective solution for mitigating the risk of wildfire ignition. However, it is a costly capital expenditure (CapEx) requiring meticulous planning and investment prioritization.

Propulsion system ignition overpressure for the Space Shuttle [PDF]

Liquid and solid rocket motor propulsion systems create an overpressure wave during ignition, caused by the accelerating gas particles pushing against or displacing the air contained in the launch pad or launch facility and by the afterburning of the ...

Impact of Aluminum Diethyl Phosphinate (DEPAL) Flame Retardant on the Thermal, Mechanical, and Fire‐Resistance Properties of an Amine‐Cured Epoxy Resin

Journal of Applied Polymer Science, EarlyView.
In this paper, an epoxy is blended with a phosphorus‐based flame retardant, DEPAL (OP935). Several thermomechanical (thermogravimetric analysis, dynamic mechanical analysis, three‐point bending, Charpy impact test) and flammability (cone calorimeter, UL94) methods are used to evaluate the effect of the flame retardant on these performance aspects ...

Quantifying Metrics for Wildfire Ignition Risk from Geographic Data in Power Shutoff Decision-Making [PDF]

arXiv
Faults on power lines and other electric equipment are known to cause wildfire ignitions. To mitigate the threat of wildfire ignitions from electric power infrastructure, many utilities preemptively de-energize power lines, which may result in power shutoffs.

An analytical study of the hydrogen-air reaction mechanism with application to scramjet combustion [PDF]

A chemical kinetic mechanism for the combustion of hydrogen has been assembled and optimized by comparing the observed behavior as determined in shock tube and flame studies with that predicted by the mechanism.
