WebSome time-dependent, shear-thinning fluids experience a permanent reduction in viscosity, making mixing time an important factor in obtaining the desired product properties. Time-dependent, shear-thickening fluids are called rheopec-tic fluids. Printing ink can exhibit rheopectic properties. Some more-difficult non-Newtonian fluids have visco- WebA low shear mixer generates three effects in the fluid: flow, turbulence and shear. Depending on the impeller type, the speed and therefore the power consumption, the lower the flow, the higher the shear. For example, for a turbine, energy is dissipated around the impeller as shear stress while a propeller will dissipate energy as axial flow.
