FORT WORTH, TX (14 July 2020) – Pointwise releases the case study, “Pointwise Enables Accurate CFD for Nuclear Reactor Rod Bundles,” explaining how Michael Böttcher of Karlsruhe Institute of Technology leverages Pointwise meshing techniques to enable accurate computational fluid dynamics (CFD) results for nuclear reactor rod bundles at stringent convergence levels, which cannot be achieved with automatic “free” meshing alone.
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.
The Karlsruhe Institute of Technology (KIT) was created to occupy a leading position worldwide in selected research areas. KIT is an institution for top-class research, excellent scientific training, lifelong learning, unlimited knowledge exchange, and a sustainable culture of innovation. https://www.kit.edu/english/index.php
