Super-Critical States of Double-Diffusive Convection under Time-Periodic Heating

抄録

Super-critical states of a horizontal double-diffusive fluid layer under time-periodic heating is investigated by truncation models. It is found that if there is no salinity stratification, the fluid layer immediately attains a periodic motion tuned with the oscillation of external temperature field. If there is a stable salinity stratification, not only a periodic motion but a nonperiodic or chaotic motion appears in the supercritical states.
