Abstract

The onset of transitional flow in cerebral aneurysms has previously been demonstrated in numerical simulations but it remains to be seen if this phenomenon is present in vivo as the detection of such flow fluctuations is difficult with the resolution of modern imaging. Here, we experimentally investigate the presence of transitional flow in physical models of aneurysms previously studied in numerical simulations. We detect the presence of transition in aneurysms through wall vibrations recordable by a microphone, and correlate it with the flow fluctuations detected in numerical simulations.
