The Evolution of Airplanes

JAP-Bejan-planeevolution.jpg

In a new paper in the Journal of Applied Physics, researchers apply the Construcal Law to airplanes, showing "that we can witness evolution in our lifetime by documenting the evolution of a flow system that is a little more than a century old: the flying 'human-and-machine species'.

Drying the maximum amount of corn with the least amount of energy—that’s what engineering manager Brent Bloemendaal of Brock Grain Systems in Frankfort, Indiana, needed to give his company a competitive edge in the marketplace. To do that, he partnered with thermodynamics experts at South Dakota State University. Using an experimental setup, assistant professor Stephen Gent of the mechanical engineering department has developed and validated a numerical model that the company calls “unique and cutting edge.”

Best-Ever Efficiency Points to Clean, Green Gas-Diesel Engine

Reitztop.jpg

The one-cylinder test engine in the basement of a University of Wisconsin-Madison lab is connected to a life-support system of pipes, tubes, ducts and cables. You might think that the engine resembles a patient in intensive care, but in this case, the patient is not sick. Instead, the elaborate monitoring system shows that the engine can convert 59.5 percent of the chemical energy in its fuel into motion — significantly better than the 52 percent maximum in modern diesel truck engines.

Study of Animal Urination Could Lead to Better-Engineered Products

A new Georgia Institute of Technology study investigated how quickly 32 animals urinate. It turns out that it’s all about the same. Even though an elephant’s bladder is 3,600 times larger than a cat’s (18 liters vs. 5 milliliters), both animals relieve themselves in about 20 seconds.
