〰️ Flow Transition Over a Flat Surface (2D)

2D Canvas simulation of the laminar-to-turbulent transition in flow over a flat surface. Adjust flow speed, viscosity and plate length to watch the real local Reynolds number cross the critical boundary-layer threshold, breaking smooth parallel streamlines into chaotic shed vortices downstream.

A 2D Canvas companion to the 3D pipe-flow Reynolds simulator, focused on flow over a flat surface instead of a pipe cross-section. Adjust flow speed, viscosity and surface length to watch the real local Reynolds number grow downstream and cross the critical boundary-layer threshold, breaking smooth laminar streamlines into chaotic shed vortices. A live HUD reports the Reynolds number and classifies the flow as laminar, transitional or turbulent.
