Effective Thermal Conductivity of Composite Foam.

Hierarchically constructed metal foam/polymer composite for high thermal conductivity

Most polymeric tribological components are inherently insulative, resulting in susceptibility to failure from frictional heating at the PV limit, which is typically reported as a product of the heat flux terms pressure (P) and sliding speed (V). This letter reports on the design of a tribological composite for increased thermal conductivity and PV limit. The control sample is an unfilled compos...

Optimization of the Effective Thermal Conductivity of a Composite

Composite materials by definition are a combination of two or more materials. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites were developed only several decades ago and have found by now intensive application in different fields of engineering (Vasiliev&Morozov, 2001). These ma...

Effective thermal conductivity of composite: Numerical and experimental study

In this paper, thermal properties of composites are investigated numerically and experimentally. In the numerical study, finiteelements method is used to modelize heat transfer and to calculate the Effective Thermal Conductivity (ETC) of the composite for three elementary cells, such as simple cubic (SC), body centered cubic (BCC) and face centered cubic (FCC). The effect of the filler concentr...

The effective thermal conductivity of wire screen

A combined experimental and theoretical investigation was conducted to examine the thermal conductivity of layers of wire mesh screen. Employing a carefully controlled sintering process, layers of sintered wire screen were examined experimentally. The experimental results indicate that the effective thermal conductivity in the z-direction (i.e., normal to the plane of the wire screen layers) fo...
