The Effect of Thermal Modulation on Double Diffusive Convection in the Presence of Applied Magnetic Field and Internal Heat Source

Abstract The investigation of thermal modulation on double-diffusive stationary convection in the presence an applied magnetic field and internal heating is carried out. A weakly nonlinear stability analysis has been performed using finite-amplitude Ginzburg-Landau model. This finite amplitude obtained at third order system. study considers three different forms temperature modulations. OPM-out phase modulation, LBMO-lower boundary IPM-in modulation. a function δ T , frequency ω difference θ. effects heat/mass transports have analyzed depicted graphically. shows that can be controlled effectively by Further, it found Rayleigh number R i enhances heat transfer reduces mass
