Abstract It is well known that the conventional couple-stress theory leaves spherical part of indeterminate. This indeterminacy problem recently resolved for fibrous composites subjected to either small or large deformations and containing a single family fibres resistant in bending (Soldatos Math. Mech. Solids, 2021, https://doi.org/10.1177/10812865211061595 ). However, remains still unsolved ...

The purpose of this research is to investigate the effects rotation on heat transfer usinginclination magnetohydrodynamics for a couple-stress fluid in non-uniform canal. When theReynolds number low and wavelength long, math formulas are used describe streamfunction, as well gradient pressure, temperature, pressure rise axial velocity perwavelength, which have been calculated analytically. many...
