arezoo ardekani graduate thesis

was carried out by former MIT postdoc Matthieu Mercier, now at the Institut de Mécanique des Fluides de Toulouse in France; MIT affiliates Brian Doyle and Michael Allshouse; and Arezoo Ardekani, now a faculty member at the University. A complete curriculum vitae of the nominee. But his group realized that if you can induce these kinds of flows on the boundaries of a floating object, you can generate forces. Colm-cille Caulfield, an applied mathematician and theoretical physicist at Cambridge University who was not involved in this research, says it is indeed surprising that this phenomenon has been overlooked for so long. I always thought, and expected, that the equivalent flows you could generate by selective heating and cooling of an object could be more significant, Peacock says.

Nominees must have completed their dissertations during the dramatic essay violin 2 previous calendar year, or by March 31 of the year of the award, at a university within the United States. The effect itself is surprisingly simple, Peacock explains: By virtue of heating or cooling the surface of an object, you change the density of any fluid next to that surface. Chandler MIT News Office May. At least one letter must be from a person who is not from the nominee's PhD granting institution. We find that addition of surfactant reduces the critical trapping radius of a drop. In the valley winds previously considered, the object was either a glacier or a valley wall heated by the sun, and the fluid was the air passing over it; in this case, its the solid wedge and its surrounding water. Caulfield adds that while the initial laboratory proof involved a small object, the effect presumably also applies to larger systems. Peacocks first study of the concept, about four years ago, focused on slow flows caused by diffusion work that demonstrated that induced boundary flows can generate small propulsive forces. Shaik a and, arezoo. This type of flow has been studied for over 100 years, but somehow, in all that time, no one had thought to do this. It may, Peacock says, even turn out to be something that living organisms have learned to harness: If a very small creature can propel itself by selectively heating or cooling itself, that could turn out to be a significant mechanism, he says. For hydrodynamics combined with diffusion based motion, we note increments ranging from 525 in the interface-retention times of surfactant-laden drops, as compared to clean drops.
