Lunch and Learn -- Dr. Datta Gaitonde -- Feb 11, 2011, 11:45am -- China Garden, Dayton
"Controlling Flowfields with Electromagnetic Fields (no moving parts!)"
Several flow control strategies using electromagnetic fields have been proposed, and many different types of actuators have been developed to achieve desired effects such as modulation of stall, transition to turbulence, mixing, noise, heat transfer, combustion flame holding and energy management. In this talk, some of the major ideas proposed will be outlined and different actuator geometries will be described. High-fidelity simulations, in conjunction with experimental data, will be used to illustrate the underlying physics and to clarify the different mechanisms by which small electromagnetic inputs can be leveraged to accomplish powerful effects.
Dr. Gaitonde is the John Glenn Professor of Mechanical and Aerospace Engineering at The Ohio State University. Until recently, he was Technical Area Leader of the High-Speed Flows Group at the Air Force Research Laboratory. He is an AIAA and AFRL Fellow, and was the recipient of the 2010 AIAA Thermophysics Award. Bring some colleagues for an interesting lunch at the China Garden Buffet!
Also, I think I remember hearing someone mention that they wanted to build a "quadracopter" at one of the meetings. Here's an interesting article in the New Scientist about teams of little bots doing neat stuff.
Daniel Mellinger and his team from the GRASP Lab at the University of Pennsylvania have developed a system that allows flying robots to construct just about any structure (see video above). A human only needs to decide on the design before an algorithm takes over to determine where parts should be placed to create it. Tiny helicopters then follow these instructions and coordinate with each other by choosing the next part placement in a list.
