Wind Tunnel Lab
by Anonymous
Type any object to create a 3D model and test it in a virtual wind tunnel, calculating drag, lift, and aerodynamic forces in real time!
About this app
Wind Tunnel Lab is an interactive 3D aerodynamics simulator for placing selected objects in a virtual wind tunnel. It estimates drag coefficient, drag, lift or downforce, side force, Reynolds number, required power, frontal area, separation point, and CdA in real time. Users can explore streamlines, smoke flow, surface pressure, ground effect, rough-surface drag crisis, and Kármán vortex shedding; the displayed values are estimates based on slender-body theory and empirical correlations, not real wind-tunnel measurements.
Use cases
- Students learning aerodynamic forces and fluid dynamics
- Teachers demonstrating Reynolds number, flow separation, and vortex shedding
- Design learners comparing vehicles, aircraft, bodies, and geometric shapes
- Users exploring how yaw, wind speed, fluid choice, and surface roughness affect aerodynamic estimates
Features
- 3D virtual wind tunnel with orbit, zoom, and object rotation controls
- Preset objects including cars, aircraft, rockets, animals, buildings, spheres, airfoils, and more
- Fluid choices including air at different temperatures and altitude plus water
- Real-time readouts for Cd, frontal area, drag, lift or downforce, side force, Reynolds number, power, separation point, CdA, and yaw sweep
- Visual modes for solid surfaces and pressure distribution, with optional streamlines and smoke flow
- Optional ground effect, rough surface, automatic rotation, and Kármán vortex shedding with Strouhal number and shedding frequency
