Abstract

In this work, a numerical analysis of the behavior of magnetorheological fluids under the influence of different magnitudes of magnetic field is carried out. The properties of these fluids are affected and modified through the application of these magnetic fields, which has many applications in the engineering area. To carry out the analysis, a circular geometry is taken on which the magnetic field acts perpendicular to the direction of movement of the fluid. The magnetorheological fluid used is Basonetic 5030. The inlet velocity of the fluid is considered to be 1.31 m/s for the geometry of 20 and 30 mm, respectively. The Bingham viscosity model is used to obtain the viscosity. For the numerical solution is used a commercial software, in which has been used a UDF for the application of the Bingham viscosity model. Among the reported results is the velocity profile and the pressure drop along the duct for magnetic fields of 0.01 to 0.5 Teslas, here is observed the influence of the magnetic effects on the magnetorheological fluid with different diameters.
磁流体流体动力特性的数值分析
本文对磁流变液在不同强度磁场作用下的行为进行了数值分析。这些磁场的作用影响和改变了这些流体的性质,在工程领域有着广泛的应用。为了进行分析,采用了一个圆形几何形状,其中磁场垂直于流体的运动方向。所使用的磁流变液为Basonetic 5030。对于20和30 mm的几何形状,流体的入口速度分别考虑为1.31 m/s。采用Bingham黏度模型计算黏度。对于数值解采用了商业软件,其中已经使用了一个UDF为宾汉粘度模型的应用。在已报道的结果中,有在0.01 ~ 0.5 tesla磁场下的速度分布和沿风道的压降,这里观察了磁效应对不同直径的磁流变流体的影响。
