Abstract

The onset of convection in a horizontal layer with a binary ferrofluid has been numerically investigated. The normal mode technique was employed to derive the non-dimensional governing equations, leading to an eigenvalue problem. Neutral stability curves were generated using various physical parameters to illustrate stability characteristics. The impact of magnetic field parameters <i>M</i><sub>1</sub>, <i>M</i><sub>2</sub>, <i>M</i><sub>3</sub>, and &psi;<sub>m</sub>, along with the helical force parameter <i>S</i> and separation ratio parameter &psi;, was examined on the stability system. An amplitude equation was derived to analyze heat transport through convection. Additionally, an increase in &psi;<sub>m</sub> resulted in a corresponding increase in the Nusselt number, indicating that higher values of &psi;<sub>m</sub> enhance heat transport.
