基于Fluent的白内障术后房水流体力学数值分析

摘要

A hydrodynamic rigid three-dimensional model of natural convection based on fluent soft-ware has been made to study microfluidic flow in the human eye.The anterior and posterior chambers are regarded as study model,which is the main channel of aqueous humor,the pressure difference and tem-perature caused by the aqueous humor in the eyeball was calculated,the cornea temperature,aqueous humor flow and gap width between iris and pupil's influence on pressure difference was analyzed.Pres-sure difference of the model after cataract surgery was calculated in different gap width between iris and pupil.Compared with the model before surgery,the hydrodynamic reasons of cataract surgery complica-tions are analyzed,which will provide a new way to study surgery complications.%应用fluent软件，建立三维自然对流水动力刚体模型，探究了眼内微流体的运动。本研究将以眼球前房和后房即房水主要流动区域作为研究模型，求解眼球内部房水流动产生的压力差和温度场，分析了眼角膜温度、房水分泌流量和虹膜至晶状体的最小距离对眼内压差的影响。计算了虹膜至人工晶体不同间距下的白内障术后模型前后房眼内压的差值，通过和术前对比，分析了白内障术后并发症的水动力因素，为后续白内障术后并发症的研究提供了新的途径。
