In fluid dynamics, a Cross fluid is a type of generalized Newtonian fluid whose viscosity depends upon shear rate according to the following equation:

where is viscosity as a function of shear rate, , , and n are coefficients.

The zero-shear viscosity is approached at very low shear rates, while the infinite shear viscosity is approached at very high shear rates.[1]

It is named after Malcolm M. Cross who proposed this model in 1965.[2][3]
