摘要
磁性液体靶向药物是磁性液体在生物医学领域一个重要应用.建立了磁性液体靶向药物的模型,利用COMSOL Multiphysics有限元软件对磁场-流场进行了数值模拟,计算了磁性液体靶向药物的雷诺数,根据临界雷诺数对应的临界速度,得出了磁性液体层流与絮流相互转化的规律,更有利于磁性液体靶向药物在生物医学及在其他领域中的应用.
Ferrofluid targeted drug is an important ferrofluid application in biomedical field.The physical model of ferrofluid targeted drug is built, the coupling between magnetic field and fluid field is numerical simulated by COMSOL Multiphysics, the Reynolds number of ferrofluid targeted drug is calculated, the critical velocity is obtained from critical Reynolds number and the transformation rule between laminar flow and turbulent flow is obtained.This research results of ferrofluid targeted drug can be applied to the biomedical field.
