Flexible Meshing Enables Accurate CFD for Nuclear Reactor Rod Bundles — Another Fine Mesh

Accurate fluid flow modeling of nuclear reactor rod bundles is essential and extremely challenging with exacting standards for the mesh to deal with the geometric complexity and near-wall physics. The tightly packed rods with wrapped wires, mainly used in liquid metal cooled systems, that contact the rods provide a challenging geometry into which well-defined boundary […]

The Physics of River Prediction

From here, beginning follows:

Rivers support life and fuel civilization. They provide water for drinking, irrigate food crops, and help build everything from cars to computers. Their waters drive hydroelectric turbines that generate clean energy. Rivers have even supported nuclear physics developments that changed the course of a war: The hydroelectric complexes of the Columbia Basin Project and the Tennessee Valley Authority enabled energy-intensive uranium and plutonium refinement for the Manhattan Project.

Rivers have always been crucial transportation pathways. The exploration, settlement, and economic development of the Americas depended acutely on river navigation. The Danube serves as a trade route in Europe, much as it did for the Romans 2000 years ago, and today it carries commercial freight across the continent….

Case Study: Accurate Performance Predictions for Marine Propellers — Another Fine Mesh

This case study presents the benchmark validation of CFD simulation results of the Potsdam Propeller Test Case (PPTC) using CFD Support’s TCFD flow solver with a Pointwise mesh. PPTC is a marine propulsor that was extensively measured by SVA Potsdam. The aim of this benchmark was to evaluate the combined use of TCFD with Pointwise […]
