WindTunnel Free

Turn your device into a wind tunnel simulator ! 

Draw obstacles and watch the fluid flow around. Experiment with different sizes, shapes, aerodynamic profiles and see what happens !


Visualize airflow with smoke, particles, or observe pressure field, velocity. The simulation engine also computes an approximation of lift and drag.

The Wind Tunnel free app lets you play with the fluid and understand physics effects. 
Fluid motion is computed by solving Navier-Stokes equations, at high definition and in real-time thanks to optimized code taking the most out of CPU and GPU performance.

Observe the mechanism of lift/drag over an airfoil, and how it stalls when the angle of attack increases (use two-finger rotate gesture to rotate the scene).

This demo version includes 3 pre-defined scenes: airfoil, rocks or torus.

Choose between different visualization modes : Smoke, pressure or speed, and adjust input speed/ fluid viscosity.

In the "torus" mode you can draw/erase your own obstacles, the fluid wraps around the screen.

Use the android "back" or "menu" buttons to show/hide the interface.
