Tweaking Turbine Angles Squeezes More Power Out of Wind Farms

08-17-22

A new control algorithm for wind farms that alters how individual turbines are oriented into the wind promises to boost farms' overall efficiency and energy output by optimizing how they deal with their turbulent wake. "Individual turbines generate choppy air, or a wake, which hurts the performance of every turbine downwind of them," says John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering. "To cope with that, wind farm turbines are traditionally spaced as far apart as possible, which unfortunately takes up a lot of real estate." [Caltech story]

Michael Gonzalez Receives 2022 Henry Ford II Scholar Award

06-23-22

Michael Gonzalez, advised by Joel Burdick, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering; Jet Propulsion Laboratory Research Scientist, is one of four recipients of the 2022 Henry Ford II Scholar Award. Michael is interested in the crossover between Mechanical Engineering and Computer Science, focusing specifically on the widespread applications of robotics. This summer, Michael will be working as a SURF fellow under Professor Soon-Jo Chung with a focus on revamping the ARCG’s autonomous flying ambulance. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Lab Earthquakes Show How Grains at Fault Boundaries Lead to Major Quakes

06-07-22

By simulating earthquakes in a lab, Caltech engineers have provided strong experimental support for a form of earthquake propagation now thought responsible for the magnitude-9.0 earthquake that devastated the coast of Japan in 2011. "Our novel experimental approach has enabled us to look into the earthquake process up close, and to uncover key features of rupture propagation and friction evolution in rock gouge," says Vito Rubino, research scientist and lead author of the Nature paper. The Nature paper is titled "Intermittent lab earthquakes in dynamically weakening fault gouge." Rubino and his co-authors Nadia Lapusta, Lawrence A. Hanson, Jr., Professor of Mechanical Engineering and Geophysics, and Ares Rosakis, Theodore von Kármán Professor of Aeronautics and Mechanical Engineering, show that so-called "stable" or "creeping" faults are not actually immune to major ruptures after all, as previously suspected.

What Is the Future of Wind Energy?

04-21-22

Humans have used windmills to capture the force of the wind as mechanical energy for more than 1,300 years. Unlike early windmills, however, modern wind turbines use generators and other components to convert energy from the spinning blades into a smooth flow of AC electricity. In this video, John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering discusses the future of wind energy technology. [Caltech story]

Student-Led Lunar Architecture Team Named Finalist in NASA Competition for Second Consecutive Year

04-12-22

Caused by collisions from asteroids, comets, and other astronomical objects, lunar craters give our moon its characteristic pockmarked façade. These craters hold the materials necessary for building sustained human settlements on the moon. Accessing the materials inside lunar craters is no easy task. NASA seeks new ways of getting around the moon that do not rely on wheels. The agency's Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge asks university teams to go beyond wheeled rovers and create new solutions to the problem of traversing lunar craters. A team of more than 30 Caltech undergraduates in the Division of Engineering and Applied Science is among seven 2022 BIG Idea finalists. [Caltech story]

Gunnarson and Dabiri Teach AI to Navigate Ocean with Minimal Energy

12-09-21

Engineers at Caltech, ETH Zurich, and Harvard are developing an artificial intelligence (AI) that will allow autonomous drones to use ocean currents to aid their navigation, rather than fighting their way through them. "When we want robots to explore the deep ocean, especially in swarms, it's almost impossible to control them with a joystick from 20,000 feet away at the surface. We also can't feed them data about the local ocean currents they need to navigate because we can't detect them from the surface. Instead, at a certain point we need ocean-borne drones to be able to make decisions about how to move for themselves," says John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering.
