In this study, a numerical simulation of airflow while pronouncing a phrase /usuimisosiru/ with velopharyngeal closure based on cinematic volumetric data was performed. The results indicated that the air stream path was affected by the velopharyngeal closure. Principle morphological factors were selected to achieve articulation of the consonant, which was the constriction ratio of the velopharyngeal...
Stents are meshed tubes used to treat narrowed or weakened arteries. It is observed that the geometrical change created by a deployed stent may influence regional characteristics and blood flow. Restenosis can occur after the stent deployment due to neointimal proliferation. In this paper a new stent design based on a regular stent was proposed to modify the wall shear stress (WSS) of existing stent...
Computational fluid dynamics (CFD) study of the blood flow in the coiled cerebral aneurysm is one of powerful tools to explore the treatment mechanism of the endovascular coiling. Although several computational techniques were proposed to represent the realistic coil configuration in the aneurysm for the CFD studies, the CFD methodology for the blood flow analysis in the densely coiled aneurysm is...
