DESCRIPTION:Exploring the linear stability of core-annular flow with ferr
 ofluids: the role of magnetic fields and an axial rod Sarah Ferguson Bri
 ggs\, Imperial Abstract: The theoretical analysis of core-annular flow (
 CAF) holds significant importance in our understanding of fluid transpor
 tation\, oil extraction\, and respiratory airflow dynamics. Here\, the l
 inear stability of a CAF comprising of two concentric ferrofluid layers 
 of different magnetic susceptibility\, centred on a rod that runs along 
 the axis of a cylindrical pipe is explored. Ferrofluids are stable collo
 idal fluids\, consisting of magnetic particles suspended in a carrier so
 lution. They behave as an ordinary Newtonian fluid\, but in the presence
  of a magnetic field they become magnetised. Originally developed by NAS
 A for vibration dampening purposes\, ferrofluids have since been employe
 d in diverse applications ranging from audio speakers to magnetic drug d
 elivery systems. Their widespread use stems from their receptiveness to 
 magnetic fields\, which allows for precise control\, their remarkable he
 at transfer qualities\, and their adaptability to various shapes and con
 figurations. This talk focuses on the impact of using ferrofluids in a C
 AF\, where an axial pressure gradient drives the flow in both fluids\, a
 nd the system is subject to an azimuthal field generated from a current 
 running through the rod. Moreover\, upon removing the field\, the system
  reverts to a rod-CAF configuration for two viscous fluids\, and novel r
 esults are found solely due to the addition of the rod. It will be shown
  that the introduction of both the rod and magnetic field can have stabi
 lising and destabilising effects on CAF\, depending on the parameters of
  the system. For online Click here to join the meeting.
