U of Akron supercomputer verifies gas permeation model in elastomer

ERJ staff report (DS)

Columbus, Ohio – An Akron researcher is designing computer prediction models for gas permeation through elastomers. The aim is to test potential new docking seals that will better preserve breathable cabin air for astronauts living aboard the International Space Station and other NASA spacecraft.

Garafolo recently analysed a two-piece silicone elastomer seal, using the IBM 1350 Glenn computer cluster at the Ohio Supercomputer Centre (OSC). His model simulated air leakage through the elastomer, taking into account the effects of gas compressibility and variable…
