Mathematical Modelling and Numerical Simulation of Electrorheological Devices

Modeling, Simulation and Optimization of Electrorheological Fluids

“…has been used in ENGELMANN et al [2000], HOPPE and MAZURKEVICH [2001], HOPPE et al [2000] in combination with a potential equation for the electric potential ψ (E = −∇ψ) to provide numerical simulations of steady electrorheological fluid flows. In the spirit of RAJAGOPAL and WINEMAN [1992,1995], RUZICKA [2000] has developed a model that takes into account the interaction between the electric field and the fluid flow (see also RUZICKA [1996, 2001]).…”

“…Due to their fast response to outer electrical fields, electrorheological fluids are much better suited for automotive shock absorbers than conventional oils. In fact, electrorheological shock absorbers feature a much wider characteristics than conventional ones and thus allow for an ideal adaptation to different road conditions and driving styles (cf., e.g., BAYER [1997b], BÖSE, HOPPE and MAZURKEVICH [2001, FILISKO [1995], GAVIN et al [1996a,b], HOPPE, LITVI-NOV and RAHMAN [2003,2007], HOPPE et al [2000]). Figure 4.11 (left) displays the longitudinal section of an electrorheological shock absorber.…”
