Pointwise Enables Accurate CFD for Nuclear Reactor Rod Bundles
Obtaining accurate computational fluid dynamics (CFD) for nuclear reactor rod bundles can be extremely challenging due to the complex geometry of the rods and wrapped wires. Automatic unstructured meshing techniques do not provide enough control over the mesh for the wire-wrapped rod bundles. Multiple Pointwise meshing techniques were used to capture the complex geometry. A fully structured mesh was used near the boundaries, and a hex-dominant unstructured mesh was used away from the boundaries to enable an accurate CFD solution for a 19-rod nuclear reactor rod bundle with ANSYS CFX. Pointwise provides a great deal of control and different techniques that can be used to make high-quality meshes for extremely complex geometries.
