| Popis: | Study of the rheological property of water, hydrocarbon and diester based magnetic fluids is done with and without magnetic field. Experimental study is made using the concentric cylinder type rotating viscometer which is operated within the strong magnetic field to clarify the effects of magnetic field, temperature and shear rate on thee rheological characteristics of the magnetic fluids. The above magnetic fluids are Newtonian in the case of no magnetic field. In the case of applied magnetic field, the observed flow curve for hydrocarbon based fluid is still Newtonian. On the otherhand, the water based and diester based fluids show pesudoplastic behaviour. Empirical formulae based on the theoretical consideration of the laminar flow between rotating concentric cylinders are obtained. |
