Nonlinear convective analysis of a rotating Oldroyd-B nanofluid layer under thermal non-equilibrium utilizing Al2O3-EG colloidal suspension

摘要: In this paper, we examine a layer of Oldroyd-B nanofluid for linear and nonlinear regimes under local thermal non-equilibrium conditions the classical Rayleigh-Benard problem. The free-free boundary condition has been implemented with flux nanoparticle concentration being zero at edges. Oberbeck-Boussinesq approximation holds good rotational effect Coriolis term is included in momentum equation. A two-temperature model explains among particle fluid phases. criteria onset stationary convection derived as function non-dimensionalized parameters involved including Taylor number. assumed negate possibility overstability due to absence opposing forces responsible it. Nusselt number obtained utilizing weak theory terms various pertinent steady transient mode, depicted graphically. main findings signify that rotation stabilizing on system. stress relaxation parameter $ \lambda_1$ inhibits whereas strain retardation \lambda_2$ exhibits heat transfer Al2O3 nanofluids.
