Hall and ohmic heating effects on radiative flow of viscoelastic nanofluids over a convective rotating rigid/stretched disk
In this article, the impacts of the Hall current on the 3D forced convection and heat transfer due to the rotation of a disk are examined. The disk's surface is considered to be rigid or stretched and the non-Newtonian viscoelastic nanofluids are assumed to be the working suspension. The convec...

| description | In this article, the impacts of the Hall current on the 3D forced convection and heat transfer due to the rotation of a disk are examined. The disk's surface is considered to be rigid or stretched and the non-Newtonian viscoelastic nanofluids are assumed to be the working suspension. The convective boundary conditions together with passively control of the nanoparticles are imposed to the disk's surface. Several important influences are considered such as Ohmic heating, thermal radiation, heat generation/absorption and Arrhenius energy. The transformed governing equations are solved numerically using the shooting technique with 4th order Runge-Kutta method. The major findings revealed that the Hall current parameter enhances the radial velocity in both rigid and stretched surface while the tangential velocity has lower features. Also, the viscoelastic nanofluid parameter causes lower behaviors of tangential velocity and nanofluid temperatures. The considered range of the Hall parameter causes an increase in the heat transfer rate by 1.73%. |
