From the beginning of its history the Royal Society has devoted much attention to the publication of communications by its Fellows and others. Within three years from the granting of the first Charter ...

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 ...

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 has famously been called "the last great unsolved problem in classical physics" by Richard Feynman. Indeed, the chaotic nature of turbulence makes it nearly impossible to predict, and we ...

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 ...

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 ...

Turbulence modeling is one of the main sources of uncertainty in CFD simulations of technical flows. This is not surprising, as turbulence is the most complex phenomenon in classical physics.

Turbulence is an omnipresent phenomenon - and one of the great mysteries of physics. A research team has now succeeded in generating realistic storm turbulence in the wind tunnel of the Center for ...
