A first-of-its-kind commercial supply ship rocketed toward the International Space Station following a successful liftoff early Tuesday, opening a new era of dollar-driven spaceflight. http://phys.org/news256879214.html Space & Earth Tue, 22 May 2012 04:20:25 EST news256879214 Air and fuel mix violently during turbulent combustion. The ferocious mixing needed to ignite fuel and sustain its burning is governed by the same fluid dynamics equations that depict smoke swirling lazily from a chimney. Large swirls spin off smaller swirls and so on. The multiple scales of swirls pose a challenge to the supercomputers that solve those equations to simulate turbulent combustion. Researchers rely on these simulations to develop clean-energy technologies for power and propulsion. http://phys.org/news235906345.html Technology Thu, 22 Sep 2011 10:33:00 EST news235906345
