Numerical Prediction of the Effective Thermal Conductivity of Perforated Hollow Sphere Structures

Abstract:

This paper investigates the thermal properties of a new type of hollow sphere struc- tures. For this new type, the sphere shell is perforated by several conical holes in order to open the inner sphere volume. The effective thermal conductivity of perforated sphere structures in a primitive cubic arrangement is numerically evaluated for different material combinations and compared to sphere structures without perforation.
