Abstract
In this paper, a novel rectangular corrugated tube is proposed for the cooling application in supercritical water reactors (SCWRs), numerically. Standard k-ε turbulence model from ANSYS-FLUENT commercial software is used for the simulation. Alumina-water is used as the nanofluid for the cooling in super- critical conditions and tried to find the optimized geometry to reach maximum heat transfer efficiency. Three geometry parameters are considered and by Central composite design (CCD) possible geometries (11 Cases) were designed and optimized by the Response Surface Method (RSM). As the main outcome, parameters a and c had more effects on the Nusselt number and nanoparticles with f ¼ 0.01 reported greatest Nusselt numbers. Also, by increasing the nanoparticles concentration from 0.01 to 0.04, the Nusselt number was decreased by 26.29% due to decreasing the heat capacity of SCW.
