Draw obstacles and watch the fluid flow around. Experiment with different sizes, shapes, aerodynamic profiles and see what happens !
Wind Tunnel is the extended version of the Wind Tunnel Free app. It adds visualization modes (turbulence, fluid direction), vga output, ability to load and save scenes, share scenes by email, rotate obstacles, adjust friction and viscosity and many more features.
Full feature list include :
• 4 actions : interact with the fluid, draw obstacles (free or straight lines), draw smoke sources, use eraser tool.
• visualization modes : particles (streamlines, streaklines and random), colored smoke (predefined stripes, streamlines and custom), pressure field, speed norm visualization, curl (visualize turbulences), velocity field (visualize speed direction) combined with speed norm or curl.
• Load/save scenes, share scenes by email, import obstacles shapes as png files.
• Rotate/move obstacles, pause simulation with gestures.
• Adjust physical parameters : fluid viscosity, obstacle friction, wind tunnel input speed.
• Predefined scenes : airfoil, cars, rocks, Kármán vortex street…
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 (over 50k grid cells on ipad) thanks to optimized code taking the most out of CPU performance.

GREAT STUFF
Schnarfengrubler
like it a bunch. recommend you hook up with a .png outfit so one doesn't have to use itunes to import.....itunes is so hogan's goat. it scrambles my desktop way bad, and loses apps, so you have to re-install at itunes notoriously sloooooow speeds....
Amazing!

This app is amazing! To be able to do flow visualization on an iPhone is very cool! I would like to see a library of NACA airfoils, maybe a way to define shapes using coordinates and formulas
Outstanding
TurboJZ
Ok, I am a mech engineer and a turbo designer, so I am a bit biased. This app is just outstanding. If you are interested in external fluid flow fun, get the Pro HD version. The price is worth the capability. I have used it to show people simple flow visualizations. Thanks for the app. Can you make one that shows flow through bends so I can show designers why a tight bend is not a good idea?
Schweet!

This is a great looking app! Great start, but not quiet a 'pro' app yet Healthy criticism: Because of the PRO title I hope to see that there is a better way of creating objects. The current 'draw wall' is barbaric at best compared to any real drawing app. It'd be nice to have a way to sketch something out. It would also be nice to be more specific on the parameter section. I think it would be nice to have this app as an actual tool more so than just a play around with wind tunnel. I really like the lift and drag calculations, and would like to see a bit more of these types of features. Great Work!
Great app

You guys have really improved this app, I would like some more options for drawing walls, but other than that is perfect.
uhhh, what?

Lowering my rating because there has not been an update to address some issues. First of all, this app is awesome! Everything about it is great except for one thing... Why are there features and modes in the regular $1.99 app that are not in the $5.99 app? Kinda feel cheated. I originally got the $2 version, then loved it so much i bought the $6 version. Then come to find out that the "Free Mode" in the $2 version is not in the pro version! What? I will change my rating to 5 stars if the dev adds this back to the pro version. Isn't the point of getting a better more expensive version to get all the features plus some? So now if i want the full experience I have to have both apps on my phone and switch back and forth. That's just not ok by me. I wouldn't have bought this version if i would have known that.
Amazing app

One of the best engineering tools ever written for a touch interface. Makes explaining aero über easy. Wow!
Good App BUT...
jdc9999
This is a good app BUT... While it works well and is perhaps accurate for fluid flow AROUND CLOSED SHAPES it does not correctly model fluid flow THROUGH shapes with openings. For example, draw a simple box and put a single small opening on the windward side of the box. The model will show flow entering that simple opening when in reality it cannot because there is no escape path for that fluid/air. Pressure inside the shape will build to prevent fluid entry. This is not mentioned anywhere and it is entirely possible with the tools available to draw scenarios like this and other "through flow" scenarios that I must assume are equally flawed. Please either 1. include this behavior correctly in your physics modeling, 2. prohibit the drawing of through flow scenarios/shapes or 3. warn users and potential buyers of this limitation. Adding this capability would be great for study of architectural natural ventilation scenarios.
