Experimental investigation of relative thermal conductivity of MWCNTs-CuO/Water nanofluids

 This work presents a model for calculating the effective ‎thermal conductivity of nanofluids. The proposed model ‎includes the effects of nanoparticles and thermal conductivity ‎base fluid.We will focus on experimental of the volume ‎concentration parameter and temperature on thermal ‎conductivity, nano-fluid combination and Multi-Walled ‎Carbon nanotubes-Oxide / Copper-paid deionized Water. This ‎water-based nanofluids, For two-step volume fractions of the ‎‎0.1, 0.2, 0.6 Percentage produced And then, Effective thermal ‎conductivity is measured precisely. In order to measure the ‎thermal conductivity of nanofluids. To measure the thermal ‎conductivity coefficient in THW method, KD2-pro and KS1 ‎probe was used, also with the fluid significantly enhancement ‎shows in thermal conductivity coefficient. Also with the fluid ‎significantly enhancement shows in thermal conductivity ‎coefficient. In lower volume fractions we observed ‎significantly increase in thermal conductivity and receive high ‎degree thermal. Due to the lack of similar studies Due to the ‎lack of similar studies to comprehensively and inefficient of ‎classical thermal conductivity, In order to estimate the thermal ‎conductivity of nanofluids An empirical model that estimates ‎the thermal conductivity of nanofluids model with deviation ‎margin is very low‏‏
