experimental investigation of viscosity of Cu-oil nanofluids

in this study experimental results of CU-oil nano fluids viscosity were investigated nanofluids viscosity changes as function of temperature and volume fraction have been measured the result show that nanofluids viscosity increase with increasing volume fraction and exponentially decrease with increasing temperature some classical model were not able to predict the experimental results of visocositys changes but the new model that was offered by masoumi et al. considers brownian motin which has a good agreement by experimental results nanofluids viscosity changes with temperature have good agreement with namburus experimental model.
