Vibration Effects on Convective Heat Transfer in a Cryogen-Filled Enclosure
The effect of vibration upon heat-transfer rates in both forced and free convection has been studied extensively for geometries including thin wires, cylinders, annuli, and flat plates [1–9]. A recent paper by Forbes, et al.  reported that free convective heat-transfer rates across a rectangular enclosure filled with water may be increased by as much as 50% in the neighborhood of certain resonant frequencies of the system. They found that the resonant frequency range at which the maximum effect on heat-transfer rates occurred could be experimentally determined by placing a pressure transducer at one end of the fluid column and recording the maximum oscillating pressure level as a function of frequency for a fixed acceleration input. This method was suggested by Schoenhals and Overcamp  in their studies of bubble formation in vibrated fluid columns. There have been no known reports in the literature of investigations into the effect of vibration on enclosures filled with a cryogen.
