A superfluid moves like a completely frictionless liquid, seemingly able to propel itself without any hindrance from gravity or surface tension. The physics underlying these materials -- which appear ...

Turbulence is one of the great mysteries of modern science. It is also one of the most important, as most of the flows we’re interested in are turbulent. In some applications, such as industrial ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
