Abstract: The effects of artificial roughness for the purpose of thermal performance improvement in pressurized water nuclear reactors are investigated. The artificial roughness consists of two-dimensional ribs parallel to the turbulent flow. The fuel rod bundle subchannel is preliminarily modeled as an annulus using the finite element method in ANSYS/FLOTRAN. The Navier-Stokes equations are solved from the SST (Shear Stress Transport) turbulence model for the simulated annulus thermal-flow. The analyses are performed f… Show more

“…Natural convection is an integral part of passive safety systems in SMR and advanced reactors. Carrilho et al [11] numerically studied the role of two-dimensional artificial surface roughness in a fuel rod bundle of pressurized water reactor (PWR) using finite element method computational tool. They observed an enhancement in the heat transfer at re-attachment point.…”
