颈动脉内血流动力学特征受向前加速度影响的数值模拟

Humans are usually subjected to acceleration with fast changing directions and magnitude in ordinary or some special situations. Previous studies have found that acceleration had physiological and path-ological influence on cardiovascular system. However, more in-depth investigations need to be done at present. In this study, the computer simulation method was used to study the hemodynamic parameter variation features laws of carotid artery under forward acceleration condition. The results reveal that acceleration has significant influence on the hemodynamic parameters including pressure, pressure gradient, wall shear stress, etc. in carotid artery, which have close relationship with physiological and pathological behavior of artery. This study provides theoretical basis for the research of carotid artery physiology and pathology under acceleration conditions, and also gives reference for human protection under acceleration conditions in aeronautic and astronautic fields.
