- Abstract:
- In this project, transport and absorption of magnetic particles for the purpose of water purification has been simulated. The used magnetic particles must be collected; otherwise they would cause additional pollution. Therefore, separation and absorption of particles is vital. The particles can be collected with an applied magnetic field. In this study different kinds of magnetic fields are applied and effect of different parameters, such as particle diameter, Reynolds number and magnetic field are considered. By increasing particle diameter and magnetic filed strength, the absorption efficiency increases. But by increasing Reynolds number absorption efficiency decreases. The particle with smaller diameter needs higher magnetic field and this limits the design of optimum absorption system. For this purpose baffle was used to tilt the fluid and particles trajectory toward higher magnetic field domain. This causes the absorption efficiency to be increased, remarkably
