In this thesis, non-Newtonian nanofluid of CuO/(CMC+water) in volume percent of ۰.۵, ۱, ۱.۵, ۳, ۴ has been simulated in a tube under constant heat flux using Fluent software. A combination of ۰.۵% (weight percent) of CMC (Chloro Methyl Cellulose) and water was used as base fluid that was non-Newtonian. At first, try to find the value of necessary properties for simulation such as viscosity, Thermal conductivity, specific heat capacity and density. At modeling step, the properties of non-Newtonian nanofluid of CuO/(CMC+water) in above volume percent were definite. Viscosity of nanofluid was function of shear rate and temperature and conduction coefficient was function of temperature intensively. Experimental quantitative values of viscosity and conduction coefficient of nanofluid were taken from previous papers, these two parameters had to be function zed before simulation in modeling software of sigma plot. The results of modeling were in good agreement with the experimental data. Density and specific heat capacity supposed to be constant in a volume percent. After modeling, laminar motion (۶۰۰≤Re≤۱۵۰۰) of mentioned nanofluids were simulated in a tube under constant heat flux with uniform velocity at input of tube. Finally، study of important hydrodynamically parameters such as viscosity, shear rate and friction coefficient were investigated for different Reynolds numbers and different volume percent nanofluids.
