Investigation of super-critical water-based nanofluid with different nanoparticles (shapes and types) used in the rectangular corrugated tube of reactors

In this paper, an optimized rectangular corrugated tube is used for the super-critical water reactor (SCWR) cooling, numerically. Al2O3, CuO, Fe3O4 and TiO2 nanoparticles in different shapes (spherical, brick, platelet and cylindrical) are considered as additives to SCW for cooling purposes, and it...
