The paper deals with the investigations of boundary layer stagnation point flow and heat transfer characteristics of an electrically conducting micropolar fluid impinging normally on a permeable horizontal surface in the presence of a uniform magnetic field. The fluid is considered to be non-Newtonian, whose flow is governed by the equations of a micropolar fluid. The governing continuity, mome...

A theory is developed for the attenuation and dispersion of compressional waves in inhomogeneous fluid-saturated materials. These effects are caused by material inhomogeneity on length scales of the order of centimeters and may be most significant at seismic wave frequencies, i.e., on the order of 100 Hz. The micromechanism involves diffusion of pore fluid between different regions, and is most...

This paper provides a comprehensive derivation for thermoelastic damping (TED) in flexural-mode ring gyroscopes, in light of recent efforts to design high rateresolution gyroscopes. Imposing an upper limit on the attainable mechanical noise floor of a vibratory gyroscope, thermoelastic damping in a ring gyroscope is extracted from the equations of linear thermoelasticity. By assuming that it is...

The properties of Rayleigh-type surface wave in a linear, homogeneous and transversely isotropic nonlocal micropolar piezoelectric solid half-space are explored. Dispersion relations for derived both charge free electrically shorted cases. Using an algorithm iteration method MATLAB software, the speed Rayleigh is computed relevant material constants. effects nonlocality, angular frequency, micr...
