Authors have studied the solidification process of heterogeneous composite materials which consist of coiled conductive solid and water.
The present study examined experimentally the melting process of these heterogeneous composite materials. Experiments were performed varying factors such as the volume ratio of conductive solid (Vd), the outer diameter (Dc) and wire diameter (D). As simple examples of these composite materials, lattice and right-angled coils were employed for measuring the temperature distribution of the materials and for observing the flow pattern.
As a result, the melting process was increased considerably with increasing Vd, and in the case of constant Vd the melting rate was promoted by increasing Dc and by decreasing D. It was observed that the natural convection based on the density inversion of the water was reduced by the lattice and right-angled coils.
