Abstract

Dynamic expressions for bulk and shear viscosity coefficients are obtained on the basis of statistical theory and a model of a two-component system. The dependence of the coefficients of shear viscosity of magnetic fluids based on water, kerosene, and undecane on the frequency and magnitude of an external magnetic field is calculated from the selection of potential energies for intermolecular and dipole–dipole interactions, the radial distribution functions, and the effect of an external magnetic field. The regions of frequency dispersion for the coefficients of shear viscosity of the studied fluids are determined, and the magneto–viscous effect in magnetic fluids is considered.

磁性液体中剪切粘度系数的频散和磁粘性效应

摘要

根据统计理论和两组分系统模型，获得了体积和剪切粘度系数的动态表达式。基于分子间和偶极-偶极相互作用的势能选择，径向分布函数，可以计算出基于水，煤油和十一碳的磁性流体的剪切粘度系数与外部磁场的频率和强度的关系。以及外部磁场的影响。确定了所研究流体的剪切粘度系数的频散区域，并考虑了磁流体中的磁粘效应。
