Abstract
In this work, we have performed the computational simulation to calculate the capture efficiency of magnetic nanoparticles flowing within a fluid in a tube under magnetic field. The capture efficiency is calculated by considering the dominant magnetization and fluidic drag forces acting on the magnetic particles. Further, experiments are also performed to calculate the capture efficiency of magnetic particles experimentally in a tube of diameter 6mm under magnetic field. Iron oxide (Fe3O4) nanoparticles were synthesized via co-precipitation method and transported them in a tube with help of peristaltic pump. The value of capture efficiency, calculated through experimental data, is found to be 26 and 50%, which is slightly differ from its value (30 and 52%) calculated through mathematical model at 2 and 6 kOe magnetic field, respectively. Subsequently, the experimental results validate the mathematical model results.
