the paper aims at investigating the effects of chemical reaction and thermal radiation on the steady two-dimensional laminar flow of viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-darcian porous medium. the radiative heat flux is assumed to follow rosseland approximation. the governing equations of momentum, angular momentum, energy, ...

in this study, flow field and heat transfer of al2o3-cu/water micropolar hybrid nanofluid is investigated in a permeable channel using the least square method. the channel is encountered to chemical reaction, and a constant magnetic field is also applied. the bottom wall is hot and coolant fluid is injected into the channel from the top wall. the effects of different parameters such as the reyn...

The present investigation is concerned with the propagation of waves at an imperfect boundary of heat conducting elastic solid and micropolar fluid media. The amplitude ratios of various reflected and transmitted waves are obtained in a closed form due to incidence of longitudinal wave (P-wave), thermal wave (T-wave), and transverse wave (SV-wave). The variation of various amplitude ratios with...

The study of the problem of Magneto Hydrodynamic viscous flow due to a shrinking sheet of Micropolar fluids has been solved numerically by using SOR method with Simpson (1/3) Rule. The similarity transformations have been used to reduce the highly nonlinear partial differential equations of motion to ordinary differential equations. The resulting equations are then integrated by using appropria...

Negative Poisson’s ratio polymer foams derived from reticulated open cell foams exhibit large size effects in torsion and bending. Effective moduli increase as diameter decreases in contrast to the prediction of classical elasticity. Size effects of this sort are predicted by Cosserat (micropolar) elasticity in which points can rotate as well as translate and distributed moments are incorporate...
