What Hydrodynamic & Fluid Simulation got wrong, from 60 theses

Summary written by a model from the records below: The records document various modeling breakdowns and computational bottlenecks encountered across hydrodynamic and fluid simulation studies. Researchers frequently found that oversimplified physical assumptions, defective boundary formulations, turbulence closure errors, and numerical scaling limitations prevented models from accurately capturing fluid behavior. These records come from graduate theses, 2021 to 2026, each labeled with its degree where the repository states it, and each links to its thesis. They were extracted by language models reading the full text, so treat each as a lead to read, not a verdict.
