Abstract

Experiments on ice contact melting within a rectangular enclosure under vibrating conditions are performed. Isothermal wall condition is maintained on the test cells with aspect ratios of 0.4, 1.0. and 2.5, respectively. It is shown that melting rates are increased under vibrating conditions and melting enhancement is proportional to the acceleration of vibration. Compared to the stationary experiments, the maximum melting rate enhancement of 170 % is observed. Aspect ratio plays an important role in melting process and the lowest melting rates occur in both stationary and vibrating conditions for aspect ratio of 1.0. The relative melting enhancement by vibration for both high and low aspect ratios are significant. The increase in melting due to vibration is more pronounced for the low Stefan numbers. Preliminary experiments show that horizontal vibration can be more effective than vertical vibration to enhance the melting rate.
