| Abstract: | The effect of magnetic field and a non-uniform temperature gradient on the Marangoni convection in a horizontal fluid layer,heated from below and cooled from above with a constant heat flux was investigated.A linear stability analysis was performed to undertake a detailed investigation.The influence of various parameters on the onset of convection was analyzed.Six non-uniform basic temperature profiles were considered and some general conclusions about their destabilizing effects were presented. |
| Keywords: | Marangoni convection non-uniform temperature magnetic field Galerkin procedure perturbed solutions |
