Phase diagram in a continuum model of the classical Heisenberg ferromagnet: mean spherical approximation

Sokolovska, T.G. - In: Physica A: Statistical Mechanics and its Applications 253 (1998) 1, pp. 459-472

The continuum Heisenberg model of spin fluid is considered. The pair correlation functions and the single-particle distribution function of ferromagnetic state are obtained by the self-consistent solution of the Ornstein–Zernike and the Lovett equations in the mean spherical approximation. On...

Heat transfer enhancement by magnetic nanofluids—A review

Nkurikiyimfura, Innocent; Wang, Yanmin; Pan, Zhidong - In: Renewable and Sustainable Energy Reviews 21 (2013) C, pp. 548-561

Magnetic nanofluids (MNF) constitute a special class of nanofluids that exhibit both magnetic and fluid properties. The interests in the use of MNF as a heat transfer medium stem from a possibility of controlling its flow and heat transfer process via an external magnetic field. This review...

Effects of oscillatory shear flow on chain-like cluster dynamics in ferrofluids without magnetic fields

Yamada, Y.; Enomoto, Y. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 1, pp. 1-11

Brownian dynamics simulations of interacting magnetic particles in a quasi-two-dimensional ferrofluid system are performed at zero temperature, under the influence of oscillatory shear flow in the absence of external magnetic fields. Starting from chain-like clusters of the particles, we study...
