Effect of g-jitter on heat transfer

In a gravity-free environment, and in the absence of radiation, heat transfer in a fluid medium is effected by pure diffusion. However, with a small but fluctuating gravitational field, characteristic of g-jitter, this situation may change. Such a field produces a fluctuating body force if density gradients are present. This results in a fluid flow with both fluctuating and time-independent components. The investigation is centered upon the heat transfer from a sphere, maintained at a constant temperature.
