Thermal Resistance of particle laden polymeric Thermal interface materials
Journal of Heat Transfer-transactions of The Asme, 2003Co-Authors: Ravi Prasher, Jim Shipley, Suzana Prstic, Paul A Koning, Jinlin WangAbstract:Particle laden polymers are one of the most prominent Thermal interface materials (TIM) used in electronics cooling. Most of the research has primarily dealt with the understanding of the Thermal conductivity of these types of TIMs. For Thermal design, reduction of the Thermal Resistance is the end goal. Thermal Resistance is not only dependent on the Thermal conductivity, but also on the bond line thickness (BLT) of these TIMs. It is not clear which material property(s) of these particle laden TIMs affects the BLT and eventually the Thermal Resistance. This paper introduces a rheology based semiempirical model for the prediction of the BLT of these TIMs. BLT depends on the yield stress of the particle laden polymer and the applied pressure. The BLT model combined with the Thermal conductivity model can he used for modeling the Thermal Resistance of these TIMs for factors such as particle volume faction, particle shape, base polymer viscosity, etc.

Borehole Thermal Resistance of U-tube borehole heat exchanger
Geotechnique Letters, 2016Co-Authors: Hossam Medhat Abuel-naga, R. R. Al-chalabiAbstract:Thermal Resistance of U-tube borehole heat exchangers (UBHE) is one of the factors that controls their design. Several equations are available in the literature to estimate the Thermal Resistance of UBHE. However, these equations produce different results and no definitive recommendation is available regarding their validity. The aim of this study is to assess numerically the validity of these equations and identify their recommended working conditions.
