The performance of heat transfer on a car radiator can be improved by using nanofluids as working fluids.In this study analyzes the of heat transfer performance of Al2O3/water nanofluids that pass through cylindrical pipes in 3D using Cake / Pie Markers the CFD simulation method for single phase approach.This Connection Tube research studied the effect of nanofluid concentration 0.1, 0.5, 1 and 1.

5% on the heat transfer coefficient.The Reynolds number is varied between 9000 to 23000 and the ambient temperature is constant.The results showed that 1.5% Al2O3/water nanofluid increasing heat transfer coefficient up to 5.7% compared to base fluid.
