Rahul Arun Receives 2020 Henry Ford II Scholar Award
05-28-20
Mechanical Engineering student Rahul Arun, advised by Professor Aaron Ames, Bren Professor of Mechanical and Civil Engineering and Control and Dynamical Systems, and Beverley McKeon, Theodore von Karman Professor of Aeronautics, is a recipient of the 2020 Henry Ford II Scholar Award. Rahul's academic interests lie at the intersection of theoretical, numerical, and experimental fluid mechanics, with an emphasis on turbulent flows. This summer, he will be working as a SURF fellow under Tim Colonius, Frank and Ora Lee Marble Professor of Mechanical Engineering, to conduct fast and adaptive numerical simulations of vortex ring collisions. In the more distant future, his plan is to attend graduate school. 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.

EAS Remembers Allan Acosta
05-19-20
Allan Acosta, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering, Emeritus, who spent 50 years at Caltech and helped launch the Institute's present day Mechanical Engineering option, passed away on May 18, 2020 at the age of 95. Allan joined the faculty in 1954 after having obtained his BS '45, MS '49, and PhD '52 degrees in Mechanical Engineering from Caltech. He collaborated with Chris Brennen, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering, Emeritus, on a project for NASA to eliminate the instability caused by a phenomenon known as "pogo oscillation" from the Space Shuttle design. Allan was a much-admired teacher and mentor who influenced many generations of students. He served as the Executive Officer of Mechanical Engineering from 1988 to 1993. He was the author of a popular textbook, Fluid Flow: A First Course in Fluid Mechanics, which he co-authored with Rolf Sabersky. Allan received numerous honors and awards, including election as a member of the National Academy of Engineering and as a Fellow of the American Association for the Advancement of Science.

Microstructures Self-Assemble into New Materials
03-03-20
A new process developed at Caltech makes it possible for the first time to manufacture large quantities of materials whose structure is designed at a nanometer scale—the size of DNA's double helix. Pioneered by Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, "nanoarchitected materials" exhibit unusual, often surprising properties—for example, exceptionally lightweight ceramics that spring back to their original shape, like a sponge, after being compressed. Now, a team of engineers at Caltech and ETH Zurich have developed a material that is designed at the nanoscale but assembles itself—with no need for the precision laser assembly. "We couldn't 3-D print this much nanoarchitected material even in a month; instead we're able to grow it in a matter of hours," says Carlos M. Portela, Postdoctoral Scholar. "It is exciting to see our computationally designed optimal nanoscale architectures being realized experimentally in the lab," says Dennis M. Kochmann, Visiting Associate. [Caltech story]

Team CoSTAR Takes First Place in Underground Robot Competition
02-27-20
A team including Caltech researchers and JPL earned top honors in the DARPA Subterranean Challenge. Whether robots are exploring caves on other planets or disaster areas here on Earth, they need to be able to navigate a location and seek out objects of interest without access to GPS or human guidance. The Subterranean Challenge tests this kind of cutting-edge technology. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, the Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering and JPL research scientist, and the leader of the Caltech campus section of the CoSTAR team. [Caltech story]
