Chain-induced effects in the Faraday instability on ferrofluids in a horizontal magnetic field | V. V. Mekhonoshin

15 Dec 2003 | Journal: | Phys. Fluids, vol. 16(4), 925 (2004). DOI: 10.1063/1.1649757 | Subject: | Fluid Dynamics; Soft Condensed Matter | physics.flu-dyn cond-mat.soft | Abstract: | The linear stability analysis of the Faraday instability on a viscous ferrofluid in a horizontal magnetic field is performed. Strong dipole-dipole interactions lead to the formation of chains elongated in the field direction. The formation of chains results in a qualitative new behaviour of the ferrofluid. This new behaviour is characterized by a neutral stability curve similar to that observed earlier for Maxwell viscoelastic liquids and causes a significant weakening of the energy dissipation at high frequencies. In the case of a ferrofluid with chains in a horizontal magnetic field, the effective viscosity is anisotropic and depends on the field strength as well as on the wave frequency. | Source: | arXiv, physics/0401073 | Services: | Forum | Review | PDF | Favorites |
