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
