The results of contact melting experiments in rectangular enclosures with phase change materials (PCM) of n-octadecane are reported with and without vibration. Isothermal wall condition is maintained on the top, bottom and two side walls of the test cells, while the remaining front and back walls are well insulated by double-layer Plexiglas. The cross sections of test cells are 52.2 mm x 130.5 mm, 82.5 mm × 82.5 mm, and 130.5 mm × 52.2 mm, respectively. The solid-liquid interface contour is videotaped to obtain the melted volume fraction. It is shown that melting rates are increased under vibrating conditions and melting enhancement is increased with the acceleration of vibration. Compared to the stationary experiments, the maximum melting rate enhancement of 95 percent is observed. Aspect ratio is an important parameter for contact melting with and without vibration. Preliminary experiments also show that the horizontal vibration increases the melting rate more than the vertical vibration.
