A CFD study on the effect of size of fuel sphere on PBR core
CFD, pebble bed, heat transfer
In this work, a thermal-hydraulic investigation of N2 as a coolant in a pebble bed reactor core has been performed using a porous media approach. Three different diameters of fuel sphere have been employed for the numerical simulations. The pebble bed reactor is a kind of packed bed reactor whose core is a long right circular cylinder with a height of 3.5 m and an outer diameter of 3.7 m. The finite volume method was used to solve the governing equations using ANSYS FLUENT 14.5. Several important thermal-hydraulic parameters have been investigated consisting of the coolant and solid temperatures, density, pressure drop, and the coolant temperature.
