Flow resident time
in the aneurysms vs. curvatures

Aspect rate

Flow resident time is stagnation time of the flow in the aneurysm. Resident time was about 5.6 times different in aspect ratio 1 and 2 in curvature 0. It is thought that resident time may be important factor of aneurysm rupture. If resident time can be measured by numerical method, it will be vary useful in medical treatment.
