Over the past few years, many motorbikes in the MotoGp have featured wings on their front fairings. These are known as aerodynamic wing kits. Why? How do they affect the aerodynamics and downforce of the motorbike? Does having more than one produce better effects? And what angle should they be set at? Find out here in this podcast!

How do car diffusers work? What is the difference between a car without a diffuser, a car with a regular venturi diffuser, one with guiding vanes, and even front diffusers?

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 Street. Find out here in this podcast! If you wan...

Motorbikes are often used in cycling races to film the race, but how much do they affect cyclists who are drafting behind them in their wakes? How is the drag affected? Find out here in this podcast!

Butterflies use the clap and fling approach to fly, but how does it exactly work? At what points during the flapping do thrust and lift get created? And do their wings' flexibility affect the flow physics? Find out here in this podcast!

Traditionally, to break the sound barrier, you make your aircraft pointy. But that method is almost 100 years old. Can you use plasma to help mitigate the shock wave instead?

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 you want to help support us in making educati...

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 aerodynamics of the airfoil? Find out here! If you w...

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!

Most airliners have spoilers on their wings. What do they do though? How do they affect the lift, drag, and pitching moment of the wing? How does the spoiler's deflection angle and length affect the wing's aerodynamics? Find out here!

Turbofans are very precise pieces of equipment and the inlet greatly affects the quality of the flow that will go through to the compressor, and subsequently, the entire efficiency of the turbofan.

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!
