RESUMO

The thermal design of the various engineering applications plays a prominent role in deciding the overall efficiency of the system. Nowadays, nano fluids have attracted the interest from the researchers due to its excellent thermo physical properties. There were several researches emphasising the importance of two phase materials and nano fluids in the effective thermal design, but none have attempted to integrate both for analyzing their combined potential thermal benefits. This research paper has aimed to formulate the general analytical expression using unit cell approach for the evaluation of Effective Thermal Conductivity (ETC) of two phase system which comprise of solid and liquid with nano particles as a third phase dispersed in the liquid phase (so called nano fluids). The expressions are evaluated for different samples (Packed beds and foams dispersed in nano fluid) and compared with the experimental results of conventional two phase system. The combined effects of influencing parameters on two phase materials with the static and dynamic mechanisms of nano fluids have been studied and validated with the standard models. The present model is better suit for predicting ETC of two phase system in different combinations with nano fluids.
