CFD has been approaching a brick wall in terms of computational power, but this new CFD method makes the resources you need to get accurate results far fewer than ever before. What is it? Based on the paper: Grid Convergence Property of Three-Dimensional Measurement-Integrated Simulation for Unsteady Flow behind a Square Cylinder with Karman Vortex…

The Mars ingenuity was the first powered aircraft to ever fly on another planet. But, it faced very strange conditions. The atmosphere was very thin, the Mach numbers were high, and the Reynolds numbers were low. That resulted in shocks at very low Reynolds numbers. How does that affect the aerodynamics of the helicopter's blades?Find out here!If y…

Gurney flaps have a massively positive effect on an airfoil's lift. And they are seen on many airplanes. There is also a new type of vortex generator, but it is more like tubercles, being investigated. So, there is a chance that both of these flow control devices will end upon the same wing. Do they work well together? How do they affect the aerody…

Turbofans, and airplane engines in general, are very important parts of the plane. But, we still don't completely understand how they affect the aerodynamics of a wing and the entire airplane. When we test them in wind tunnels, they are simplified models, as they are in CFD. What are their exact effects though?Find out here!If you want to help supp…

There are more types of winglets than you can poke a stick at. There are the common Boeing winglets, then the Airbus sharklets, but so many more. And they're used to reduce the strength of the wingtip vortex and hence the induced drag of a wing. But, do they only affect the flow near the wingtip?Find out in this podcast!CHECK OUT our new OpenFoam C…
