The document discusses using magneto-rheological fluid (MRF) to efficiently clean up oil spills. MRF is a smart fluid that can be controlled by a magnetic field. When added to oil, MRF behaves as a Newtonian fluid without a field, but forms a viscoelastic solid when a field is applied, pulling the oil-MRF mixture toward the field. This allows faster recovery of spilled oil compared to current methods. Numerical modeling of MRF flow behavior is performed to optimize the method. The research aims to minimize environmental damage from oil spills using an efficient and cost-effective recovery method.
