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 ...

Scientists at the University of Stuttgart's Institute of Aerodynamics and Gas Dynamics (IAG) have produced a novel dataset that will improve the development of turbulence models. With the help of the ...

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 ...

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.

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 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 ...

Going with the flow: does an extra term lead to a better model of turbulence? (Courtesy: iStock/Mumemories) Identifying universal laws within fluid mechanics is notoriously difficult. So it has come ...
