摘要

Abstract

In this paper

response surface methodology (RSM) based on central composite design (CCD) is applied to obtain an optimization design for the fuel rod's diameter and distance cooled by turbulent Al

-water nanofluid for a typical pressurized water reactor (PWR). Fuel rods and nanofluid flow between them are simulated 3D using computational fluid dynamics (CFD) by ANSYS-FLUNET package software. The RNG

k-ε

model is used to simulate turbulent nanofluid flow between the rods. The effect of different nanoparticles concentration is also investigated on the Nusselt number from heat transfer efficiency view point. Results reveal that when distance parameter (

) is in the minimum level and diameter parameter (

) is in the maximum possible level

cooling the rods will be better due to higher Nusselt number in this situation. Also

using the different nanoparticles on the cooling process confirms that Al

averagely 17% and TiO

10% improve the Nusselt numbers.
