Al2O3nano- particles in water with concentrations of 0.5, 1.0, 1.5, 2 and 2.5% were studied in the simulation. All thermo-physical properties of nanofluids were temperature independent. It was concluded that heat transfer coefficient increased with the Peclet number. Furthermore, it increased by increasing the concentration of nano-particles in nanofluid. The simulated data were in good agreement with the literature (with the discrepancy of less than 10%).}, keywords = {Nanofluid,heat transfer,Simulation,Circular tub}, url = {https://www.ije.ir/article_72127.html}, eprint = {https://www.ije.ir/article_72127_0dde2bc5edd6fb4c66f37f9f77842b52.pdf} }
