Slip Microrotation Flow of Silver-Sodium Alginate Nanofluid via Mixed Convection in a Porous Medium [PDF]

open access: yesMathematics, 2021
In the previous decennium, considerable applications ofnanoparticles have been developed in the area of science. Nanoparticles with micropolar fluid suspended in conventional fluids can increase the heat transfer. Micropolar fluids have attracted much research attention because of their use in industrial processes.

A Bayesian Reconstruction Method with Marginalized Uncertainty Model for Camera Motion in Microrotation Imaging

IEEE Transactions on Biomedical Engineering, 2010
Reconstruction of a 3-D structure from multiple projection images requires prior knowledge of projection directions or camera motion parameters that describe the relative positions and orientations of 3-D structure with respect to the camera. These parameters can be estimated using, for instance, the conventional correlation alignment and feature-based

Darcy–Forchheimer electromagnetic flow of entropy optimized microrotating Casson–Carreau nanomaterials

Heat Transfer, 2021
AbstractIt is apparent that non‐Newtonian nanofluids (especially, Casson and Carreau) find their ubiquitous utilization in diverse industrial processes. The magnetohydrodynamics concept is significantly implemented in the engineering design process. Darcy–Forchheimer's effect characterized by inertia and boundary effects ameliorates the rate of heat ...

Continuum metrics for deformation and microrotation from atomistic simulations: Application to grain boundaries

International Journal of Engineering Science, 2011
Abstract Motivated by a desire to incorporate micro- and nanoscale deformation mechanisms into continuum mechanical models of material behavior, we apply recently developed volume-averaged metrics to the results of atomistic simulations to investigate deformation and microrotation in the vicinity of grain boundaries.

Wellposedness and zero microrotation viscosity limit of the 2D micropolar fluid equations

Mathematical Methods in the Applied Sciences, 2011
Summary: We consider the 2D micropolar fluid equations in the whole space \(\mathbb R^2\). We prove the global wellposedness of the system with rough initial data and show the vanishing microrotation viscosity limit in the case of zero kinematic viscosity or zero angular viscosity.

A polarimetric optical microrotation sensor employing A birefringent uniaxial crystal

Microwave and Optical Technology Letters, 1991
AbstractA polarimetric sensor suited for microrotation measurements is described. Its basic component is a uniaxial crystal inside which the extraordinary wave velocity changes with rotation, thus altering the monitored polarization state of the light coming out of the crystal.

Study on Microrotating Structure Using Microwire Electrical Discharge Machining

Materials and Manufacturing Processes, 2014
This paper discusses fabrication method of the rotating structure using microwire electrical discharge machining (micro-WEDM). A high-speed rotating spindle has been designed and installed to in-house developed micro-WEDM equipment with two axis to enable the processing microrotating structure. In order to realize high-precision processing, a numerical

Horospherical coordinates for optimal Cosserat microrotations

Mathematical Methods in the Applied Sciences, 2018
This note proposes the use of horospherical coordinates to overcome the problems associated with multiple eigenvalues occurring in the Cosserat microrotation problem. The advantages of this coordinate system are argued.

Thermal deposition on magnetohydrodynamic nanofluidic transport of viscoplastic fluid with microrotations

Journal of Molecular Liquids, 2017
Abstract Background and objectives The prime focus of this investigation is to explore nonlinear radiation effects on MHD micropolar Casson fluid over a stretching surface. Impact of microrotation on flow and heat transfer characteristics has been examined under the influence of thermophoresis and Brownian motion phenomenon.
