Abstract
The original experimental data on axial distributions of the shear stress on the surface of a rod - a fuel element simulator - during fluid flow through a model of fuel assembly (FA) are presented depending on the rod diameter (9, 10, 15 mm), relative distance between the rods (1.2, 1.3, 1.4, 1.45), and number of rods (7 and 37) for the laminar, transient, and turbulent liquid flows in fuel assemblies.
