This is a theoretical/numerical modeling study of time- modulated boundary forcing of convection under conditions significantly beyond the first onset of convective instability. Time-periodic boundary temperatures as well as time-periodic vertical accelerations will be investigated. By allowing the parameters which control thermal convection to vary with time, the changes in convection as well as control to enhance or reduce convective transfer and mixing will be explored.

这是一个时间调制的对流边界强迫的理论/数值模拟研究，在明显超过对流不稳定的第一次开始的条件下。时间周期边界温度和时间周期垂直加速度将被研究。通过允许控制热对流的参数随时间变化，探索对流的变化和控制对对流转移和混合的增强或减少。
