Wildfires have become an annual destructive force with the 2018 California wildfires witnessing the tragic loss of life and $3.5 billion in damages, which unraveled communities and motivated new outlooks to safety and liability. Our solution harnesses the novel firefighting technique of real time low computation wildfire prediction simulations, through a particle based representation of …
Tracking and Fighting Fires on Earth and Beyond
Mechanical engineer Michael Gollner and his graduate student, Sriram Bharath Hariharan, from the University of California, Berkeley, recently traveled to NASA’s John H. Glenn Research Center in Cleveland, Ohio. There, they dropped burning objects in a deep shaft and study how fire whirls form in microgravity. The Glenn Center hosts a Zero Gravity Research Facility, …

What Are Fire Whirls? Researchers Examine the Behavior of These Tornado-Like Fire Columns
In a fire whirl, rising hot air twists flames into a towering pillar. Although fire whirls in wildlands are normally small, fire whirls can grow large and destructive, forming into a burning tornado, as in the case of the 2018 Carr fire in California. In this video, Assistant Professor Michael Gollner explains the characteristics of …
Heat Energy Leaps Through Empty Space, Thanks to Quantum Weirdness
If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it’s a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can’t travel if there are no atoms or molecules around. But a new study by …
Going to extremes
New research by Berkeley engineers may soon make it more practical to use battery-powered vehicles and devices in extreme temperatures, such as icy-cold winters in Minnesota or stifling-hot summers in Death Valley. Led by Chris Dames, professor of mechanical engineering, the researchers developed a thermal regulator that can improve the performance of lithium-ion batteries outside of what’s …
Berkeley ingenuity keeps lithium-ion batteries at temps even Goldilocks would love
New research by Berkeley engineers may soon make it more practical to use battery-powered vehicles and devices in extreme temperatures, such as in icy-cold winters in Minnesota or stifling-hot summers in Death Valley. Those conditions represent temperature ranges that fall outside the narrow window — typically 20 to 40 degrees Celsius — needed for a …
ME Professor Carlos Fernandez-Pello Awarded the Howard W. Emmons Invited Plenary Lectureship by the IAFSS
