Sinusoidal vertical vibrations to the system are assumed to affect a time-dependent gravitational field for the onset of natural convection. A linear stability analysis is performed to obtain the Rayleigh number as a function of system parameters. The effect of chemical reaction parameter (Damköhler number) on Rayleigh number is depicted graphically and is discussed in detail. |
