Establishing the Caltech Field Laboratory for Optimized Wind Energy (FLOWE)

05-17-10

John O. Dabiri, Associate Professor of Aeronautics and Bioengineering, has purchased two acres of land north of Los Angeles, where he is establishing the Caltech Field Laboratory for Optimized Wind Energy (FLOWE). The goal is "to extract significantly more wind energy from a given parcel of land than is currently possible... [by taking] advantage of constructive aerodynamic interference between closely spaced vertical-axis wind turbines." says Dabiri whose inspiration for this project came from observation of schooling fish.

Professor Knauss Receives the 2010 Timoshenko Medal

05-04-10

Wolfgang G. Knauss, Theodore von Kármán Professor of Aeronautics and Applied Mechanics, Emeritus, has been selected to receive the 2010 Timoshenko Medal from the American Society of Mechanical Engineers "for fundamental contributions to the mechanics of fracture, covering mixed-mode fracture, dynamic fracture, and interface and adhesive fracture; and the characterization of material response and failure at the microscale, with an emphasis on experimental mechanics." The Timoshenko Medal was established in 1957 and is conferred in recognition of distinguished contributions to the field of applied mechanics.

Caltech Researchers Create "Sound Bullets"

04-22-10

Alessandro Spadoni, Postdoctoral Scholar, and Chiara Daraio, Assistant Professor of Aeronautics and Applied Physics, have built a nonlinear acoustic lens that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." The combination of the acoustic lens and sound bullets have "the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems," says Professor Daraio.

Beverely McKeon Shares Her Perspectives on Controlling Turbulence in Science Magazine

03-26-10

Beverley McKeon, Assistant Professor of Aeronautics, shares her perspectives on controlling turbulence in the March 2010 issue of Science. Professor McKeon states, "more than 100 years after Osborne Reynolds's seminal experiments on the transition of flow through a pipe from a laminar to a turbulent state, the exact physical mechanism that drives this phenomenon still vexes the fluid mechanics community."

Anthony Leonard and Richard Flagan Elected Members of the 2010 Class of the NAE

02-18-10

Anthony Leonard, Theodore von Kármán Professor of Aeronautics, Emeritus, and Richard C. Flagan, Irma and Ross McCollum-William H. Corcoran Professor of Chemical Engineering and Professor of Environmental Science & Engineering; Executive Officer of Chemical Engineering, have been elected members of the 2010 class of the National Academy of Engineering (NAE). NAE membership honors those who have made important contributions to engineering theory and practice, and those who have demonstrated unusual accomplishments in the pioneering of new and developing fields of technology. Election to the NAE is one the highest professional distinctions an engineer can receive. Professor Flagan was elected to the NAE "for leadership in invention, measurement, production, and technology of aerosols" and Professor Leonard was elected "for contributions to simulation of turbulence, new vortex methods of flow simulation, and understanding of flow-induced vibration."

EAS Remembers Tsien Hsue-Shen

11-02-09

Qian Xuesen (also known as Tsien Hsue-Shen) (Aeronautics PhD '39), passed away on October 31, 2009. He was a student of Professor Theodore von Kármán and one of the founders of the Jet Propulsion Laboratory. "Dr. Tsien Hsue-Shen was one of the great scientist-engineers of the past century. He played an important role in the history of Caltech and the development of the Jet Propulsion Laboratory. We are also very proud of his many accomplishments in China." said President Chameau.

Sandra Troian and Mathias Dietzel Solve Decade-Long Mystery of Nanopillar Formations

10-23-09

Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and Dr. Mathias Dietzel have uncovered the physical mechanism by which arrays of nanoscale pillars can be grown on polymer films with very high precision, in potentially limitless patterns. "This is an example of how basic understanding of the principles of physics and mechanics can lead to unexpected discoveries which may have far-reaching, practical implications," said Ares Rosakis, Division Chair and Theodore von Kármán Professor of Aeronautics and Mechanical Engineering at Caltech. "This is the real strength of the EAS division." [Caltech Press Release] [video] [Download real player]

John Dabiri and Kakani Katija Link Tiny Sea Creatures to Large-scale Ocean Mixing

07-29-09

John Dabiri, Assistant Professor of Aeronautics and Bioengineering, and graduate student Kakani Katija have discovered a new mechanism that explains how some of the ocean's tiniest swimming animals can have a huge impact on large-scale ocean mixing. Dabiri describes, "we've been studying swimming animals for quite some time, the perspective we usually take is that of how the ocean—by its currents, temperature, and chemistry—is affecting the animals. But there have been increasing suggestions that the inverse is also important—how the animals themselves, via swimming, might impact the ocean environment." Ares Rosakis, the Theodore von Kármán Professor of Aeronautics and Mechanical Engineering and chair of the EAS Division described the research as, "truly reflective of the type of exciting, without-boundaries research at which Caltech engineering professors excel."
