Computational Fluid Dynamics Aids Aerospace Apps

Just a few years ago, the use of computational fluid dynamics (CFD) in most aerospace companies was restricted to pure research or troubleshooting problems with existing designs. But in the past few years, newly available CFD tools are fully embedded in the mainstream mechanical design environment and hence much easier, faster and less expensive to use.

NASA Study Shows How Oil Production Impacts Climate

When and how global oil production will peak has been debated, making it difficult to anticipate emissions from the burning of fuel and to precisely estimate its impact on the climate. To better understand how emissions might change in the future, Pushker Kharecha and James Hansen of NASA’s Goddard In stitute for Space Studies in New York considered a wide range of fossil fuel consumption scenarios.
