Linear instability of Nanofluid with helical force

Abstract

The investigation focuses on the onset of convection in a horizontal layer saturated nanofluid with helical force. The non-dimensional governing equations is solved using the normal mode technique, resulting in an eigenvalue problem. The eigenvalue problem for
linear instability is solved using the one-term Galerkin approach which gives the analytical expression for Rayleigh number. Neutral curves are drawn for both steady and oscillatory instability for all physical parameters.
