Jet noise

R&D Magazine (Rockaway, N.J., June 30) -- Aerospace engineers from Illinois are using the National Science Foundation-supported Stampede supercomputer to explore how jets in general, like those on modern aircraft and inside the human body, generate noise. Daniel Bodony and his colleagues are trying to solve this problem using Stampede to simulate the turbulent motion generated by air moving from the jet engines and then virtually testing the shape and location of actuators and acoustic liners that can reduce jet noise.
