Numerical simulation of power law and yield stress fluid flows in double concentric cylinder with slotted rotor and vane geometries

► CFD-based measurement error analysis for vane and double concentric cylinder rheometers. ► A vane rheometer is much more sensitive to the power index of fluids than the DCCR/SR. ► The DCCR/SR can measure yield stress fluids with high accuracy than a vane rheometer.
