Using large-scale numerical calculations, we explore the proper orthogonal decomposition of low Reynolds number turbulent pipe flow, using both the translational invariant (Fourier) method and the ...

The Vortex Particle Method (VPM), a meshless vortex flow simulation approach, is gaining traction for its efficient simulation of unsteady vortex wakes evolution that is shed by aircrafts, rotors and ...

For more than a century, the field of fluid mechanics has posited that turbulence scales with inertia, and so massive things, like planes, have an easier time causing it. Now, new research has shown ...

An experimental facility has been constructed to investigate a fully developed turbulent pipe flow over a large range of Reynolds numbers. In the past many experiments (Nikuradse, 1932; Laufer, 1954 ...

Turbulence is generally regarded as a permanent feature of many fluid flows. That assumption is challenged by the claim that shear turbulence has a limited lifetime — albeit sometimes a very long one.

In order to push flight technology beyond the supersonic regime, fundamental research on viscous hypersonic flow will be essential. It is widely recognized that this research must have both a strong ...

Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid — in this case, the flow of air over the wings — becomes chaotic and unstable. For more than a century, the ...
