RESUMO

The thermal convection in Walters B’ viscoelastic fluid is considered in the presence of a uniform vertical magnetic field and uniform rotation. For the case of stationary convection, Walters B’ viscoelastic fluid behaves like a Newtonian fluid. It is found that rotation has a stabilizing effect, whereas the magnetic field has both stabilizing and destabilizing effects. Graphs have been plotted by giving numerical values to the parameters, depicting the stability characteristics. The rotation, magnetic field, and viscoelasticity are found to introduce oscillatory modes in the system that were nonexistent in their absence.
