Optimization of thermal conductivity in composites loaded with phase-change materials

What is it about?

This work focuses on identifying the thermal conductivity of composites loaded with phase-change materials (PCMs). Three configurations are studied: (1) the PCMs are divided into identical spherical inclusions arranged in one plane, (2) the PCMs are inserted into the matrix as a plate on the level of the same plane of arrangement, and (3) the PCMs are divided into identical spherical inclusions arranged periodically in the whole matrix.

Why is it important?

The results highlight the influence of the number of the spheres introduced into the studied composite. Meanwhile, we also studied the influence of the incidence angle of flux, compared with these planes, on the thermal behavior of composite. The results obtained indicate that the ideal composite conductivity is obtained if the load PCM is divided into multiple spheres arranged in a plane parallel with the flux and, particularly, if it contains the diagonal of the entry face.
