This term is a product among the non-Darcy coefficient, the fluid density and the square of flow velocity.

The results show that the couple stress fluid flow behavior depends on not only the coefficient of viscosity, but also the material constant responsible for the couple stress parameter.
Accurate understanding and calculating the total fracturing fluid leak-off coefficient is both key problem to the fracturing design and the important matter to the analysis after fracturing.
