Aircraft morphing, especially in the case of the variable camber airfoil, has potential from the viewpoints of both fundamental aerodynamics and flight application. In the field of aerodynamics, the ...

(Nanowerk Spotlight) Flow separation is a common phenomenon affecting aircraft, wind turbine blades, micro aerials, and underwater vehicles. Owing to its unsteady flow profile, such separation is ...

Numerical computations are carried out for the NREL S809 airfoil. The flow is modelled using an unsteady incompressible Reynolds Averaged Navier-Stokes solver. Two turbulence models (SST k/ω of Menter ...

From experimental correlations of airfoil and flap pressure distributions, it is observed that flow separation is likely to occur when the canonical pressure recovery coefficient (Cpr) exceeds a ...

Natural laminar flow is a known means of reducing aircraft drag and energy consumption, but its practical implementation is difficult on commercial airliners that cruise at transonic speeds and ...

A novel FlowViT-Diff framework that integrates a Vision Transformer (ViT) with an enhanced denoising diffusion probabilistic model (DDPM) for super-resolution reconstruction of high-resolution flow ...

Airfoils work because the higher speed of air going over the top surface results in lower air pressure than the slower air beneath. If you drilled a hole top to bottom in an airfoil, which direction ...

Natural laminar flow (NLF) airfoils are key to achieving optimum performance and fuel efficiency in many vintage and current production turbine-powered business aircraft. NLF is not a new discovery.

We’ve probably all experimented with a very clear demonstration of the basic principles of lift: if you’re riding in a car and you put your flattened hand out the window at different angles, your hand ...

Gas turbines are critical in modern power generation and propulsion systems, with compressor performance being paramount to overall efficiency. Compressor airfoils and blades, essential for ...
