Effects of Couple Stress on the Growth Rate of Rayleigh- Taylor Instability at the Interface in a Finite Thickness Couple Stress Fluid [PDF]
Journal of Applied Fluid Mechanics, 2010 In this paper the effects of couple stress fluid on the control of Rayleigh-Taylor instability at the interface between a dense fluid accelerated by a lighter fluid is studied. A simple theory, based on fully developed approximations, is used to derive

Global Stability For Double-Diffusive Convection In A Couple-Stress Fluid Saturating A Porous Medium [PDF]
Studia Geotechnica et Mechanica, 2019 We show that the global non-linear stability threshold for convection in a double-diffusive couple-stress fluid saturating a porous medium is exactly the same as the linear instability boundary.

Determination of the Spherical Couple-Stress in Polar Linear Isotropic Elasticity [PDF]
, 2023 It is well known that the conventional couple-stress theory leaves the spherical part of the couple-stress indeterminate. This indeterminacy problem is recently resolved for fibrous composites subjected to either small or large deformations and ...

On the Exact Solutions of Couple Stress Fluids [PDF]
Advanced Trends in Mathematics, 2014 Exact solutions of the momentum equations of couple stress fluid are investigated. Making use of stream function, the two-dimensional flow equations are transformed into non-linear compatibility equation, and then it is linearized by vorticity function. Stream functions and velocity distributions are discussed for various flow situations.

Trends in Sciences, 2022 In this article, the exact solution for a couple stress fluid flow past a fluid sphere filled with a couple stress fluid is considered using interfacial slip on the boundary. The velocity is expressed with regard to the stream function. The external velocity and internal velocity are alongside the drag coefficient.
