Multi-Phase Blood Flow Modeling in Intracranial Aneurysms Considering Possible Transition to Turbulence

According to the Dorland Medical Dictionary a cerebral aneurysm is an abnormal bulge or ballooning in a blood vessel supplying the brain. Aneurysms can rupture and bleed into the area between the brain and the surrounding membrane. A noticeable percentage of the human population, typically 2 to 5% depending on the country, harbors a cerebral aneurysm, but only about 0.1% of those aneurysms rupture annually [1].
