Abstract
In this study, direct contact melting with asymmetric load is investigated experimentally and analytically. In experiment, rectangular parallelepiped PCM and rectangular heating plate were used so that the flow in the thin liquid film could be treated as the two dimensional problem in rectangular coordinates. The PCM on the heating surface was melted under various asymmetric loads, while total load acting on the PCM and brine temperature were kept constant. Then, time dependency of the height and the inclination of the PCM were measured. In analysis, the system was formulized and calculation was carried out, while the moment, the total load, the brine temperature ware set at constant values that were similar to the experimental conditions. The melting process progressed keeping the force balance between the pressure in the liquid and the loads at all times. As the result, it was found that an average heat flux into the PCM was independent of the moment acting to the solid and it was decided by the total load and the brine temperature, experimentally and analytically Moreover, analytical results of the time dependency of the melting amount and the inclination of the PCM coincided with experimental one for all conditions.
