Title: Onset of instability in Rayleigh-Benard configuration

Abstract: Thermal instability of a fluid layer, confined between two horizontal rigid boundaries, with time-periodic temperature distribution is studied with the help of the Floquet theory. The time-dependent part of temperature is expressed as a Fourier series. Disturbances are assumed to be infinitesimal. Only odd solutions are considered. Numerical results for the critical Rayleigh number are obtained at various Prandtl numbers and for various values of the frequency. Comparisons are made with the known results.
