Biconvective transport of magnetized couple stress fluid over a radiative paraboloid of revolution

Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering, 2022
In the present study, the physical features of the bioconvective MHD flow of a couple stress fluid over an upper horizontal surface (i.e. surface shaped like a submarine or any (uhsp) aerodynamical automobile) is analysed by considering radiation and ...

Three‐dimensional non‐Newtonian couple stress fluid flow over a permeable stretching surface with nonlinear thermal radiation and heat source effects

Heat Transfer, 2022
This study is a study of three‐dimensional couple stress Casson fluid flow with nonlinear thermal radiation and heat source effects. The convective heat and mass transfer analysis is applied to a porous stretching sheet.

Mathematical modeling for peristalsis of couple stress nanofluid

Mathematical methods in the applied sciences, 2022
The current article investigates the magnetohydrodynamic (MHD) radiative peristaltic flow of a couple stress nanoliquid in a symmetric channel. Thermally convective and zero mass flux conditions are imposed on flexible channel walls.

Size-dependent thermoelastic damping analysis in nanobeam resonators based on Eringen’s nonlocal elasticity and modified couple stress theories

Journal of Vibration and Control, 2022
Thermoelastic damping has emerged as a critical issue in the modeling and design of micro and nanomechanical systems. Therefore, an extensive research interest is being devoted towards the reduction in thermoelastic damping for micro and nanomechanical ...

A non-classical theory of elastic dielectrics incorporating couple stress and quadrupole effects: part I – reconsideration of curvature-based flexoelectricity theory

Mathematics and mechanics of solids, 2021
A new non-classical theory of elastic dielectrics is developed using the couple stress and electric field gradient theories that incorporates the couple stress, quadrupole and curvature-based flexoelectric effects.

Stress and couple stress in foams

Computational Materials Science, 2003
Abstract Even in the range of small elastic deformations the behavior of foams is not well described by only two elastic constants. Usually the manufacturers give values of the material parameters depending on the loading conditions. This problem is investigated on a microscopic scale by a simple beam model. It has been found that this approach shows

Numerical Simulation of Nonlinear Thermal Radiation on the 3D Flow of a Couple Stress Casson Nanofluid Due to a Stretching Sheet

, 2021
Little is known on the three-dimensional flow of a couple stress Casson fluid conveying nanoparticles when the significance of Lorentz force, chaotic gesture of those minute particles, and thermophoresis are significant.

Couples Coping with Stress

European Psychologist, 2009
The primary objective of the study was to increase understanding of interpersonal dimensions of stress and coping within married couples. Our sample included 82 couples living in a stepfamily context. Data were collected using structured telephone interviews and twice-daily questionnaires for a period of 1 week.
