September 2015: Spinning Paper Wings Meet CFD

The theme for this month's newsletter is spinning paper wings. Let Computational Fluid Dynamics (CFD) be your guide as we progress from a simple spinning paper sheet to a tumblewing, and finish up with a control method (walkalong) for a tumblewing.

Tumblewing Meets CFD

Although a sheet of paper can be made to fly by spinning, it isn't always reliable. By adding winglets and flaps with 4 simple folds we can improve the stability of the wing and in so doing produce a tumblewing. How do the aerodynamics of a tumblewing compare with a sheet of paper? It just so happens Computational Fluid Dynamics (CFD) can help, just as it did with the simulation of the spinning sheet of paper.

Spinning Paper Sheet Meets CFD

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.

August 2015: Are You Ready For CFD?

You've heard that Computational Fluid Dynamics (CFD) might be able to help with your fluid dynamics application, but you are unsure how to proceed. Then fear not, we've got you covered this month with articles on how to get started with CFD and clarifications on our Caedium CFD offering. Also, see whether CFD has a role in drone design.

Get Started With CFD

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.

July 2015: Summer Cycling, Support, and More CFD Fun

Summer's here at Symscape HQ and therefore it's Tour de France time, so find out why cycling has gone all in on aero. Unrelated - but an important issue - do you know why Computational Fluid Dynamics (CFD) can be so costly? If not, learn more about the role of technical support. Then to finish up with even more fun than last month, see how Caedium simulated the flow through the pipe networks from a classic screensaver of yesteryear.

CFD Support Worth Paying For

Computational Fluid Dynamics (CFD) software is not like other desktop applications, such as a word processor. Using a word processor to write a novel is usually undertaken without expecting that the word processor software vendor to also provide help constructing sentences and paragraphs. Yet in the CFD industry that is exactly the expectation (need) of CFD users, i.e., CFD users expect help from a CFD vendor on how to construct a model (sentences) and run a simulation (paragraphs).
