Intrinsic apparent viscosity and rheological properties of magnetorheological grease with dilution oils

In this study, the principal rheological properties of the magnetorheological grease (MRG) is experimentally investigated with various types and percentages of dilution oils. The stability in terms of oil separation and rheological properties of the natural plant-based dilution oil; castor oil was c...
