| Abstract: | Using a new algorithm based on particles aggregation theory to calculate the thermal conductivity of nanorefrigerant,the thermal conductivities of two kinds of copper-water nanofluids were calculated and contrasted with experimental data.The results show that the algorithm is feasible.The thermal conductivities of five kinds of copper-R22 nanorefrigerants were calculated.The calculated data were analyzed.It was concluded that the particles aggregation theory and resistance network method are effective tools to research the thermal conductivity of nanorefrigerant. |
