Hv. Ly et al., Dynamic simulation of the temporal response of microstructure formation inmagnetorheological fluids, INT J MOD B, 15(6-7), 2001, pp. 894-903
Efficient numerical simulations of microstructure development in magnetorhe
ological (MR) fluids are conducted. The simulations, which are based upon a
fast multipole olgorithm, treat the magnetic inclusions as two-dimensional
continuum magnetic entities. The development of microstructure is quantifi
ed by computing and recording the time evolution of the effective permeabil
ity of the composite fluid. Such a principle has been previously exploited
for the experimental measurements of microstructure development [Jolly, Ben
der and Mathers, ERMR'97, Yonezawa, Japan 1997]. As was observed experiment
ally, numerical simulations reveal the evolution of microstructure to be mu
ltimodal in nature. Unlike the experiments, the numerical simulations affor
d us the ability to observe the physical mechanisms associated with various
modes.
