fl0wINN: Multi-Scale Turbulent Flow Investigation using Neural Networks

fl0wINN is a Python package designed for investigating multi-scale turbulent flows using physics-informed neural networks (PINNs). This project aims to provide a flexible and extensible framework for simulating various fluid dynamics problems, including channel flow, lid-driven cavity, and flow over an airfoil.
