Damaging Volcanic Ash Stays Well Beyond Welcome

The video discusses the impact of volcanic ash on air traffic, highlighting how ash can damage aircraft engines. Researchers, supported by the National Science Foundation, are studying the aerodynamic properties of ash to understand how long different particles remain in the atmosphere. Experiments in a wind tunnel at the University of New Hampshire demonstrate how particle shape affects suspension time. The findings are used to develop computer models for better forecasting ash behavior, aiding in predicting when skies will be clear for safe air travel after eruptions.

What was one of the major consequences of the Iceland volcanic eruption?

• It caused a tsunami.

• It resulted in a massive earthquake.

• It led to a global temperature rise.

• It halted air traffic across northern Europe.

Why are ash particles a concern for aircraft engines?

• They can cause the engines to freeze.

• They can melt and interfere with engine operation.

• They can cause the engines to overheat.

• They can increase fuel consumption.

In the wind tunnel experiments, which shape of particles stayed airborne the longest?

• Round balls

• Cubes

• Crumples

• Flakes

What is one of the goals of the research team regarding ash particles?

• To find a way to eliminate ash from the atmosphere.

• To understand how particles interact with each other and environmental factors.

• To develop new types of aircraft engines.

• To create a new type of ash-resistant material.

How will the research findings help in the future?

• By creating new volcanic eruption prediction models.

• By improving the design of aircraft engines.

• By enabling more accurate predictions of ash dispersion for safe air travel.

• By developing new types of volcanic ash.
