Until now it had been assumed that, once a flow of a fluid has become turbulent, turbulence would persist. Researchers have now shown that this is not the case. In their experiments they managed to ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Trajectories in time traced out by turbulent puffs as they move along a simulated pipe and in experiments, with blue regions indicate the puff "traffic jams." The images on the left are closer to the ...

If one looks at many practical fluid flows, either around bodies (flow of air over an airplane wing) or through conduits, (flow through pipes), the problem of turbulence presents itself in almost ...

This release is available in German. When a flow reaches a certain speed, things get turbulent: The fluid or the gas no longer flows in an orderly fashion but whirls around wildly. However, in ...

Russian analysts are testing the characteristics of a laminar-flow nacelle proposed for the high-thrust Aviadvigatel PD-35 engine. The PD-35 is a planned evolution of the PD-14 engine developed for ...
