    • Abstract


      In this analysis, the collective impact of external electric field and internal heat generation on the onset of thermal convection of Jeffery fluid in a porous matrix is investigated analytically.Utilising linear stability hypothesis reliant on the normal mode process, a dispersion relation is derived and this dispersion relation is investigated for stationary and oscillatory styles of convective activities. The results reveal that the stability of the system diminishes by increasing the Jeffery parameter λ, the electric field parameter R$_E$ and the internal heating parameter S$_H$. It is also shown that the oscillatory style of convective movement has not been feasible for the problem.
