Study of temperature influence on the rheological behavior of magnetic fluids

2022 
Abstract The influence of temperature on the inertial structures in magnetic fluid was previously assumed to be based on a single mechanism. In this work, specialized rheological experiments were performed and their results have shown that different structural evolution paths can take place under the function of hydrodynamic and thermal interaction. The widely adopted Mason number was proved to be unsuitable to describe the magnetoviscous effect of magnetic fluids under different temperatures. To give a proper description on the combined effect of magnetic dipolar interaction, hydrodynamic interaction and thermal interaction in magnetic colloidal system, a novel structural number S was proposed and found to be applicable to superimposed the data under various temperatures onto a master curves.
