If fluid flow is a primary driver for your design project then Computational Fluid Dynamics (CFD) is likely to be a cost effective way to help meet your goals. You could outsource your CFD to consultants, but in the long run it usually pays to do it yourself.

I don’t think anyone would argue with the fact that paper airplanes are simple (and fun!), but what is the simplest paper airplane that can still fly? I give you a single rectangular piece of paper without any folds that will gently spin around its longest horizontal axis if released with a long edge parallel to the ground. Next, what is the simplest Computational Fluid Dynamics (CFD) method that can capture the essence of the spinning paper? I give you the Moving Reference Frame (MRF, also known as the frozen rotor method) option for CFD. Combine the two and you arrive at an interesting simulation of a simple phenomenon.

New to Computational Fluid Dynamics (CFD)? Then you've come to the right place. Becoming productive in CFD can be a daunting task. However, as with all long term goals, if you break it down into smaller, achievable tasks, in no time you'll be up to speed and ready for production level work. Assuming you are familiar with the fluid dynamics of your application, then let's begin.

It used to be that to design and build a flying machine was an expensive endeavor, what with pilots, wind tunnel tests, prototypes, etc. Not any more though - welcome to the brave new world of Unmanned Autonomous Systems (UAS) or Unmanned Autonomous Vehicles (UAV) or, more popularly, simply drones. How did we get to this point and where is it going? What role, if any, will Computational Fluid Dynamics (CFD) play in this drone future?
