Clement Klienstreuer, a professor of mechanical and aerospace engineering at North Carolina State University, is using computer simulation and fluid dynamics for designing experimental blood vessels, arteries, and bypass grafts. With funding from the National Institutes of Health and the National Science Foundation, he is heading up a team of vascular surgeons and engineers aiming to design a better arteriovenous access graft. The grafts serve as portals through which blood passes for kidney dialysis and other procedures. Conventional designs are Teflon-based and prone to frequent failure. One of the keys to the new graft is a graft hood, which complicates its design, but improves blood flow. For a copy of the paper describing the new graft geometry, contact Linda E.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
