Effective thermal conductivity of the heterogeneous lyophobic nanosystems for the usage in thermomechanical energy devices

This paper presents theoretical results of thermal conductivity of the heterogeneous lyophobic nanosystems characterized by structure that consists of interpenetrating components. More specifically, this structure is a liquid and a solid with communicating pores non-wet by the liquid. It has been shown in this paper that forced intrusion of liquid which takes place during compression of the system can be well described by using the model of intersecting pores.

► A new thermodynamic system was proposed to study the thermal conductivity. ► A physical model was proposed to describe the filling of pores by the liquid. ► Model “interpenetrating components” was used to calculate the particle conductivity. ► Model “closed inclusions” was used to calculate the system conductivity in general.
