CFD Simulation of Single Phase Mixing in a 4x4 Rod Bundle with Different Spacers

Enhancing heat transfer between fuel rods and coolant is one of the main goals of nuclear engineering. Spacer grids equipped with mixing vanes are placed inside nuclear fuel assemblies to enhance the lateral velocities of the flow inside the sub-channels and, also, increase the lateral mixing betwee...
