The effect of transverse vibration on the natural convection heat transfer in a rectangular enclosure

The study was carried for a Raghiely number between (3.77 - 10.8)*107 with applied heat flux between (20 - 45) Watt. The vibrational experimental measurements were carried out for different frequency ratio (0.87-1.6) and vibrational Rayleigh number ranged between (0.12 - 2.7)*107 . The results of the heat transfer inside the enclosure without vibration show a very close agreement with the published one.
