Product Viscosity Versus Shear
Feb 11 2013 06:50 PM |
Steve Hall
in Fluid Flow
Many products are known to be “shear thinning,” which is a term given to materials that exhibit a decrease in viscosity when force is exerted. The viscosity of pseudoplastic fluids decreases with shear, and recovers quickly when the shear is removed. Examples include paper pulp in water, latex paint, molasses, and pharmaceutical suspensions (such as certain cough syrups).
