Experiment-based Comparison of Prediction Methods for Pump Head Degradation with Viscous and Power-law Fluids [PDF]
Chemical and Biochemical Engineering Quarterly, 2022 Although several methods are known to calculate pump performance with highly viscous and non-Newtonian fluids, research has not yet determined all the key parameters of these predictions. It is unclear how these parameters depend on the pump geometry and

Fluids, 2017 The flow of a non-Newtonian, power-law fluid, directed normally to long, two-dimensional horizontal bodies, is considered in the present note. It is found that for low Reynolds numbers ( Re ≤ 0.1 ) and a low power-law index (shear-thinning fluids ...

Investigation on Asymmetric Instability of Cylindrical Power-Law Liquid Jets
Energies, 2019 An investigation has been performed to reveal the breakup mechanism of three-dimensional power-law cylindrical jets with different mode disturbances. It is observed experimentally that the asymmetric mode disturbances could prevail over the counterpart ...

On the Stationary Flow of the Power Law Fluid in 2D [PDF]
Journal of Applied Analysis, 2002 The author considers stationary flow of heat-conducting power-law shear-thinning fluid in a bounded two-dimensional domain. For homogeneous boundary conditions, the author proves existence of at least one weak solution (the uniqueness remains an open problem).

International Journal of Applied Mechanics and Engineering, 2020 This paper deals with the investigation of time dependent boundary layer flow of a modified power-law fluid of fourth grade on a stretched surface with an injection or suction boundary condition. The fluid model is a mixture of fourth grade and power-law

On the Stokes Paradox for Power-Law Fluids
ZAMM, 2001 We study a purely viscous flow of a non-Newtonian fluids obeying the power-law in an exterior domain. We prove that for pseudo-plastic fluids the Stokes paradox does not take place, while for the dilatant fluids it takes place in any space dimension $n$ if the flow index is larger or equal to $n$.

On Hele–Shaw flow of power-law fluids
European Journal of Applied Mathematics, 1992 This paper reviews the governing equations for a plane Hele–Shaw flow of a power-law fluid. We find two closely related partial differential equations, one for the pressure and one for the stream function. Some mathematical results for these equations are presented, in particular some exact solutions and a representation theorem.
