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 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.

Flows of Newtonian and Power-Law Fluids in Symmetrically Corrugated Cappilary Fissures and Tubes [PDF]
, 2018 In this paper, an analytical method for deriving the relationships between the pressure drop and the volumetric flow rate in laminar flow regimes of Newtonian and power-law fluids through symmetrically corrugated capillary fissures and tubes is presented.

Journal of Mechanical Engineering and Sciences, 2019 In a recent study, the Two-Layer Crossing Channels Micromixer (TLCCM) exhibited good mixing capacities in the case of the Newtonian fluids (close to 100%) for all considered Reynolds number values.

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).

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 $n$.

Existence Theory for Stochastic Power Law Fluids [PDF]
Journal of Mathematical Fluid Mechanics, 2015 We consider the equations of motion for an incompressible Non-Newtonian fluid in a bounded Lipschitz domain $G\subset\mathbb R^d$ during the time intervall $(0,T)$ together with a stochastic perturbation driven by a Brownian motion $W$. The balance of momentum reads as $$dv=\mathrm{div}\, S\,dt-(\nabla v)v\,dt+\nablaπ\,dt+f\,dt+Φ(v)\,dW_t,$$ where $v ...

Computer algebra models the inertial dynamics of a thin film flow of power law fluids and other non-Newtonian fluids [PDF]
, 2007 Consider the evolution of a thin layer of non-Newtonian fluid. I model the case of a nonlinear viscosity that depends only upon the shear-rate; power law fluids are an important example, but the analysis is for general nonlinear dependence upon the shear-

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
