Abstract
The turbulent flow in an annular channel with streamwise inter-rod gapping is computed using Large Eddy Simulation (LES). This fundamental study is carried out with a view to investigate the vortex shedding generated at the end of the fuel rods and its impingement onto the downstream rods. The spacing between the rods is varied to study the effect of the mean flow as well as the turbulence structure revealing two distinct flow patterns analogous to the flow over the k-type and d-type roughness.
