Chain and fibrous network formation in magnetorheological suspensions
| Description | We have been looking at how suspensions of small particles interact when subjected to a magnetic field. Under these conditions they form structures which depend on the strength of the magnetic filed and the concentration of the particles. We have written computer code to follow individual particles as the structures assemble and to measure how many other particles are in contact with each particle. We have developed equations which describe the structures formed in dilute suspensions. This has now been presented at conference and published in a good peer-reviewed journal. We have developed equations which describe the structures formed in more concentrated suspensions. A manuscript discussing this work is under preparation. We will use the equations that we have developed to help explain what structures can be achieved under different conditions and why. |
