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 or turbulences. The simulation engine also computes an approximation of lift and drag.

The Wind Tunnel app lets you create beautiful wind tunnel scenes, 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. You can for example 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).

Full feature list include :

• choose between 4 actions (lower right button): interact with the fluid, draw obstacles, use eraser tool, or add rotors.

• visualization modes : particles (streamlines, streak lines and random), colored smoke (predefined stripes, streamlines or streak lines), pressure field, speed norm visualization, curl (visualize turbulences), velocity field (visualize speed direction) combined with speed norm or curl. 

• Save/load your own designed scenes.

• Rotate obstacles with two-finger rotate gesture.
• Change smoke color by tapping twice at the top of the wind tunnel (when smoke is on and in “interact” mode )

• Adjust physical parameters : fluid viscosity, obstacle friction, wind tunnel input speed.
• Switch between two simulation modes: wind tunnel or “free” mode where fluid wraps around screen.
• In “Params”, then “Perf.param”, adjust the grid size and smoke resolution (high-end devices are able to compute larger grid sizes, allowing you to draw thinner obstacles).

• Predefined scenes : airfoil, cars, rocks, Kármán vortex street…

Use the android “back” button to close any interface screen, or to undo the previous action (previous draw/erase).
Use the android “menu” button to hide/show the bottom button bar.

The simulation software will not run on some old devices (it requires NEON instructions), if in doubt, try first the free version, WindTunnel Free.

A very good app. Would love some drawing tools though (paint style) Drawing perfect shapes by hand is near impossible.

Saswat Mohanty

Mind blowing Can't believe my eyes, an app of less than an MB size can do these many wonders. So realistic and fantastic simulations. I can spend hours on this app. Great work dev. One of the best purchase ever.

clement Ding

Stunning app Stunning App! Draw a circle and you can see karman vortex street!!! although it's hard to draw a perfect circle..... would be great if they can add some drawing tool, like drawing a circle, a line, a polygon, etc. Will follow... Can I also see non dimensional drag and lift coefficients?

Tom Layton

I need more airfoil functions with alpha changes and standard airfoil libraries. It will come someday, I can't wait :)

Andrew Kerr

Fun and informative I have been waiting for this app on android for several years since I came across it on apple. Well worth the wait. Working as a sailing coach it is a great tool to explain what makes the boat go and get people to experiment. A drawing tool to get better shapes is the only way I can see to improve it. Possibly being able to import shapes from other programmes? However still a clear 5 stars

Alistair Coulstock

Excellent! Been waiting for this since I found the Apple version. Nice work developer!

Anders Mølgaard Holtze

Intuitive and illustrative I work as an engineer in a physical wind tunnel and love to play around in this simple app! The solver however does not conserve mass, so for certain cases the flow magically disappears...

Wessel Du Plooy

Been waiting so long for this Had it on iOS for months waiting for an Android version. Great app!

Evan Smith

Great! Really good app. Very flexible and fun to use. I'd love to know more about the solver, turbulence model, etc.

John Osorio

Nice As a CFI I see a lot of potential for this app but I wish there was more airfoils to choose from since its not easy to draw a nice airfoil the first time. Being able to modify the airfoil's characteristics might be a good idea too. Thank you and keep the good work.

Erik Fernandez

The wait is over I've been waiting for the android version to be realesed for quite a while; it does not dissapoint.

John Dunn

Excellent app. I was planning to build a small wind tunnel to help my students understand the principles of lift and fluid dynamics. This app has saved me a lot of effort! I would like the ability to have a library of different airfoil shapes but otherwise it suits my purpose very well.

Stephen Cardno

Wow, great app Now I can play with wind, very cool

Steve Barker

Could be great. Could do with set of basic preset shapes, fluid presets, fit to grid when drawing and erosion simulation.

Brian D

Needs DXF Import It would be awsome if you could import shapes via DXF or some other format to be able to look at variations more precisely. Otherwise a really cool app.

thomas gaskins

Omg I am amazed how good this app is

Jayant Mukhopadhaya

Great app Could do with some airfoil libraries and it would be great if it didn't erase everything when the screen times out

Shainath Kalamkar

Wonderful Must have app!

Jacob DeRosia

Awesome app Great app, but I just wish there was a line tool in addition to free draw.

Alexander De Rosa

Awesome science fun! Great visualization tool and a load of fun to play around with.

Leonardo Bjork

Its fun to mess with It could give some practical visual to the understanding of aerodynamics. You know a base on flow, restriction, lift or high and low pressures. Haven't seen to much it can do yet but as a simple learning aid its well worth its cost at this time. It has a potential of being so much more though and hopefully with out getting into the stupidity range of pricing that kills it where only the high end critics buy one or 2 a shut it down.... just saying. My fingers are crossed for good luck.

Aaron Thake

Fantastic, just what I was looking for

Mark Krebs

OK this is great. Now you know what to do with all those extra flops on your phone. Please add CM?

Tom Sharp

Fascinating Brilliant stuff

Maxim Pryhodko

Problem Program crashes when l try to use "Erase" tool.

Alexey Ageev

The best wind tunnel application Very much appreciated w.tunnel simulator. Best in class for android. I wish the same for non-steady flow and aeroelastic behavior. This should be nice for divegence, flutter, galloping and buffeting. Thanks a lot dear friends!

Drew Walker

Truly Impressed Great way to learn about fluid dynamics. Does this take into account compressible vs incompressible flow? I WISH you could select or toggle that on or off. Wonderful app.

Philippe Sucosky

Educational and fun! Fantastic app to illustrate fluid mechanics concepts in the classroom. Highly recommended!

Niccolò Scaringella

Usefull and potentially great app! Nice app, usefull to all engineers who want have a quick preview of their designs. By the way more interaction tools are needed; as other users have said, a tool which allows you to create perfect figures (lines, circles and boxes) would be very usefull. I also have to report multiple crashes on my Samsung Tab S... So many... Anyway I'll put 5 stars as soon as these problems will be solved.

Jan Antonis

Excellent app. Only achieves half its potential without dxf import and drawing tools though.

Jacob Waterfield

Perfect for Flight Instructing Excited to use these to explain aerofoils in my flight instructor briefings

Fernando Baca

Is awesome but.... This would be awesome if it could do 3d

Tony Godshall

Entertaining. But not useful. Not clear how to load my own shape. Or indeed any NACA airfoil other than the one provided. Needs to be more clearly useful, not just pretty, to be a paid app.


Great features Lots of fun to experiment with. Worth every cent
