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.

</div> <div jsname="WJz9Hc" style="display:none">把你的设备变成一个风洞模拟器！绘制障碍和周围观看的流体流动。尝试不同的尺寸，形状，空气动力学配置文件，看看会发生什么！

气流可视化烟雾，颗粒，或观察压力场，速度。仿真引擎还会计算升力和阻力的近似。

该风洞免费的应用程序可以让你与流体玩和理解物理特效。流体运动通过求解Navier-Stokes方程，在高清晰度和实时感谢采取最出CPU和GPU性能的优化代码来计算。

 观察升力/阻力的机制在机翼，以及它是如何档位时的迎角增加（使用两个手指旋转手势旋转的场景）。

这个演示版本包括3预定义的场景：翼型，岩石或环面。

不同的可视化模式之间进行选择：吸烟，压力或速度，并调节输入速度/流体的粘度。

在“圆环”模式，您可以绘制/擦除自己的障碍，屏幕周围的流体包裹。

使用Android“后退”或“菜单”按钮来显示/隐藏界面。
