One-way Transmission System for Sound Waves


Postdoctoral scholar, Georgios Theocharis, and GALCIT alumnus Nicholas Boechler; working with Professor Chiara Daraio, have created the first tunable acoustic diode- a device that allows acoustic information to travel only in one direction, at controllable frequencies. [Caltech Press Release]

Wind-turbine Placement Produces Tenfold Power Increase


Field tests of John O. Dabiri, Professor of Aeronautics and Bioengineering, and colleagues' vertical-axis wind turbines have shown that the power output of wind farms can be increased by an order of magnitude—at least tenfold— by optimizing the placement of turbines on a given plot of land. "Dabiri's bioinspired engineering research is challenging the status quo in wind-energy technology," says Ares Rosakis, Division Chair and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. "This exemplifies how Caltech engineers' innovative approaches are tackling our society's greatest problems." [Caltech Press Release] [Videos of Turbines]

Yue Yang Receives 2011 Richard B. Chapman Memorial Award


Yue Yang, a graduate student working with Dale Pullin, is the recipient of the 2011 Richard B. Chapman Memorial Award. Dr. Yang has developed a novel Lagrangian formulation and multi-scale diagnostic tools to study fluid turbulence and vortex dynamics. The award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
