Cyclonic Airflow in Hexagonal Duct - HVAC and Fluid Dynamics Visualization #1337379 (License: Personal Use)

This diagram illustrates laminar-to-turbulent transition in a hexagonal duct, where incoming airflow forms a spiral vortex due to boundary constraints and pressure gradients. The blue streamlines indicate direction and curvature, highlighting core recirculation zones and exit flow stabilization. It’s commonly used to model cyclone separators, ventilation systems, or drone propeller intakes.

Used in engineering textbooks, HVAC system documentation, and fluid dynamics simulations; targets professionals and students seeking visual explanations of vortex generation in constrained geometries.
