基于计算流体动力学方法,采用Fluent软件中的雷诺应力模型和颗粒随机轨道模型,选取旋流除砂器常见工作状态,数值模拟研究了颗粒入口速度在5~15 m/s、质量浓度在10~30 kg/m^(3)变化时对旋流除砂器壁面磨损的影响,得到了旋流除砂器内壁磨损分布规律。模拟结果表明,旋流除砂器壁面磨损分布并不均匀,入口环形空间以及底流口附近磨损率较大。颗粒入口速度和质量浓度的变化对旋流除砂器壁面磨损整体分布影响较小,但入口速度的变化会改变各磨损区域内磨损最严重点的位置,入口环形空间壁面磨损位置变化最为明显,而颗粒质量浓度的变化则对壁面磨损最严重点的位置影响较小。颗粒入口速度和质量浓度的增大都会使旋流除砂器最大磨损率增大,入口速度对旋流除砂器最大磨损率的影响比质量浓度更大。

成骨不全症(osteogenesis imperfecta,OI)是最常见的单基因遗传性骨病,以反复骨折、骨骼畸形和身材矮小为特点。准确定量评估骨骼表型对判断OI严重程度、制定治疗方案和预测预后有重要意义。目前常用OI表型评估方法,如X线检查、双能X射线吸收测量仪等,难以全面反映骨微结构和骨骼生物力学性能。近年来,多种新型影像测量技术,包括骨小梁评分、高分辨外周骨定量计算机体层成像、磁共振成像等,能够定量评估骨微结构、骨骼生物力学性能,有助于全面了解OI骨骼表型信息、预测骨折风险,值得关注及应用。
