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 lowhttp://jsme.iaukhsh.ac.ir/article_528818_f76bfa24c2e72f12ef459e47ed4f5631.pdf
