Computational Fluid Dynamics (CFD) of aneurysmatic blood vessel / Masri Zairi Mohd Zin

Blood flow dynamics plays an important role in the development of aneurysms. An aneurysm is a permanent ballooning in the wall of an artery. The pressure of blood passing through can force part of a weakened artery to bulge outward, forming a thin-skinned blister. This study is to analyze the Comput...
