Talking to Turbulence

07-31-13

Beverley McKeon, Professor of Aeronautics and Associate Director of GALCIT, and her colleagues have developed a new and improved way of looking at the composition of turbulence near walls, the type of flow that dominates our everyday life. "This kind of turbulence is responsible for a large amount of the fuel that is burned to move humans, freight, and fluids such as water, oil, and natural gas, around the world," Professor Mckeon describes. They have devised a new method of looking at wall turbulence by reformulating the equations that govern the motion of fluids—called the Navier-Stokes equations—into an infinite set of smaller, simpler subequations, or "blocks," with the characteristic that they can be simply added together to introduce more complexity and eventually get back to the full equations.

Caltech's Unique Wind Projects Move Forward

06-10-13

John O. Dabiri, Professor of Aeronautics and Bioengineering, has big plans for a high school in San Pedro, military bases in California, and a small village on Bristol Bay, Alaska. "We have been able to demonstrate that using wind turbines that are 30 feet tall, as opposed to 300 feet tall, could generate sufficient power for wind-farm applications," Dabiri says. "One of the areas where these smaller turbines can have an immediate impact is in the military." The Office of Naval Research is funding a three-year project by Dabiri's group to test the smaller vertical-axis wind turbines (VAWTs) and to further develop software tools to determine their optimal placement. "We believe that these smaller turbines provide the opportunity to generate renewable power while being complementary to the ongoing activities at the base," Dabiri explains. [Learn More]

Professor Coles Passes Away

05-06-13

Donald E. Coles, Professor of Aeronautics, Emeritus, passed away on May 2, 2013 at the age of 89. Professor Coles made pioneering contributions towards our understanding of boundary layers, turbulent shear flows, bluff-body aerodynamics, and novel experimental methods in fluid dynamics. He was a member of the National Academy of Engineering and a Fellow of both the American Institute of Aeronautics and Astronautics and the American Physical Society. In 2011 he was honored with the Donald Coles Lecture in Aerospace. He remained active till his passing, working on a book on Turbulent Shear Flow that is very near completion. [Caltech Obituary]

International Scholarship Focused on Engineering Global Challenges Announced

03-14-13

The Caltech Division of Engineering and Applied Science and the USC Viterbi School of Engineering have established a new scholarship program, named after outgoing National Academy of Engineering (NAE) president Charles M. Vest at their institutions, along with six other universities around the country. "The Vest Scholarship is a superb opportunity for high-powered international graduate students to work with faculty and researchers who are international leaders in their engineering disciplines," says Chair Ares Rosakis. "At Caltech, due to its small size and strong interdisciplinary philosophy, the students will have the opportunity to work closely with not only these international leaders in engineering research, but also with their collaborators in all areas of science and technology."

Professor Clauser Passes Away

03-05-13

Francis H. Clauser, Clark Blanchard Millikan Professor of Engineering, Emeritus, passed away on Sunday, March 3, at 99 years of age. Professor Clauser, a Caltech alumnus (PhD '37), served as Chair of the Division of Engineering and Applied Science from 1969 to 1974. Upon stepping down as Chair he remained the Millikan Professor until his retirement. Although he retired in 1980, he maintained a vital presence on the Caltech campus, particularly at the Athenaeum round table, until shortly before he passed. [Caltech Release]

EAS Division Welcomes New Deputy Chair

02-08-13

Peter Schröder, Professor of Computer Science and Applied and Computational Mathematics, is the new Deputy Chair of the Division of Engineering and Applied Science. "I look forward to working with Peter over the next several years as we continue with our quest to remain a unique collaborative community of isolated singularities that sets a compelling model as a research and teaching institution," says Chair Ares Rosakis.

Professor Hornung Receives Honorary Doctorate

12-13-12

Hans G. Hornung, C. L. Kelly Johnson Professor of Aeronautics, Emeritus, has received an Honorary Doctorate from the ETH (Swiss Federal Institute of Technology, Zurich). He was conferred this honor by the Rector of ETH Zurich, Lino Guzzella at a special ceremony in the Hauptgebaeude of the ETH. Professor Hornung was recognized for his outstanding research contributions to gas dynamics of high-speed currents, especially to reflection and stability of shock waves, to the influence of real gas effects and to the laminar-turbulent transition; in addition the prize is meant as an award of his extraordinary ability to be inspiring when passing his knowledge on to his students. The other recipient of this honor was the Astronomer Royal, Sir Martin Rees, Master of Trinity College, Cambridge University. [Learn More] [Caltech Release]

Student Cold Storage Project Wins $25,000 Sustainability Prize

11-27-12

Aeronautics graduate student, Prakhar Mehrotra, has won the $25,000 Dow Resnick Sustainability Innovation Student Challenge Award (SISCA) at Caltech. His team won the prize for an elegantly simple project called Micro Cold Storage. The idea is to manufacture a portable cold storage unit, scaled to fit in a farmer’s truck, that is powered by solar panels. The project’s implications are far reaching for rural farmers in India, to clinics in Africa, to farmer’s markets in Pasadena. [Learn More]
