EMPIRICAL MODEL RESPECTING A LOCAL EXTREME OF A COURSE OF THE VISCOSITY FUNCTION

Filip P., David J., Pivokonský R.
pages 57 - +5p., full text

Almost all empirical models dealing with the flow curves of nonNewtonian fluids can be applied only in the case of monotonous course of these curves. Exceptionally it is possible to model viscosity behaviour of rheologically more complex materials if there appears, in the course of a flow curve, a global extreme. The 8-parameter model proposed enables a description of viscosity behaviour in dependence on shear rate or shear stress also for the case when an extreme (maximum or minimum) is only local.
