Scaling temperature dependent rheology of magnetorheological fluids

摘要: Magnetorheological (MR) fluids are suspensions of micron-scale magnetizable particles suspended in a carrier fluid. When field is applied, MR develop controllable yield stress and independent post-yield viscosity. However, this viscosity has substantial temperature dependence, varying by up to an order magnitude over the operating range fluid devices. We apply non-Brownian suspension theory explain result find that majority effect should be caused dependent behavior Thus, if two share same fluid, then their properties scale similarly. This first validated measuring across for custom model designed conform theory, showing scaling within 5% both Then, on series related commercially available with unknown additive content, we show MR...
