Nonsimilar equations exist in many fluid flow problems and these equations are difficult to be solved using variation of the physical parameters. The key purpose of this study is to find nonsimilarity solution of nanofluid on an exponentially shrunk sheet in the existence of micropolar nanofluid without considerations of the thermal radiation and ...

Physics of Fluids
In this paper, mechanisms that differentiate microrotation (i.e., particles' internal rotation) and vorticity in magnetohydrodynamic micropolar flows with magnetic particles are examined. Micropolar fluids are characterized by the asynchronization of the microrotation and the vorticity of the liquid carrier. When the microrotation is equal to the fluid'

AIP Conference Proceedings, 2016
The paper is devoted to detailed investigation of rotational deformation modes at the notch tip during shock loading. Using hybrid discrete-continuum approach of Excitable Cellular Automata the series of numerical experiments were conducted to simulate deformation behavior of ductile steel in the vicinities of U-, I- and V-notches.

Microrotation-augmented Energy-Minimization for 3D Nanocrystalline Cu Structures
2008Molecular dynamics simulations are frequently used to study deformation mechanisms at the nanoscale. However, the lattice orientations of grains in the starting nanocrystalline (nc) configurations are typically based on either random orientations (Van Swygenhoven and Derlet [1]; Schiotz et al.

Bridging the Gap Between Continuum Mechanical Microrotation Viscosity and Lagrangian Point-Particles
Journal of Fluids Engineering, 2013The microrotation viscosity is an essential fluid property in micropolar fluid dynamics. By considering a dilute suspension of inertial spherical point-particles in an otherwise Newtonian fluid, an explicit analytical expression for the microrotation viscosity is derived. This non-Newtonian continuum mechanical fluid property is seen to be proportional

The goal of this paper is to provide a rigorous justification of the asymptotic model proposed by Beneš et al. [Nonzero boundary condition for the unsteady micropolar pipe flow: well-posedness and asymptotics, Appl. Math. Comput. 427 (2022), Paper No. 127184, 22] for the time-dependent flow of a micropolar fluid in a thin cylindrical pipe.

AbstractThe current study is based on the effects of microrotational dynamics, microinertial effects, and temperature changes on electroosmotic peristalsis in a tapered microchannel. This has been addressed by an analytical study of heat transfer in the setting of electroosmotic peristaltic flow involving a micropolar fluid, specifically considering a ...

Investigation of steady state regarding Spin gradient and Microrotation effects on Micropolar Fluid
IJFMR - International Journal For Multidisciplinary ResearchNumerical simulations were conducted to investigate the flow of a micropolar fluid past an infinite vertical plate. A finite difference method was utilized for the numerical analysis. The study considers the behavior of the micropolar fluid in two-dimensional, unsteady flow and obtains its non-similar solutions.
