NAG Meeting 11-07-11

At this week’s NAG meeting, James Dougherty presented on his Master’s of Architectural Engineering project which involves computationally modeling the attenuation through elbows in ductwork using COMSOL.  He is comparing both square and radiused elbows, using 1″ and 2″ lining of different flow resisitivities. Data on elbow attenuation provided in the ASHRAE Applications Handbook remains sparse, so Dr. Lau and James are interested in developing a model that can provide valid attenuation data on a wider expanse of elbow configurations.

The ‘Acoustic Nugget’ of the week was shared by Andrew Hathaway … dB drag racing!  “This American Life” recently re-aired an episode on this dangerous ‘sport’.

Only two more meetings this semester!
