A phenomenological model is proposed in this paper for simulating the effect of wall friction in turbulent pipe flows.The flow in this model is divided into two regions: wall region and core region.

A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...

In pressure relief systems, accurately estimating temperature changes during fluid flow is vital for relief piping ...

Fluid flow friction factors serve as a cornerstone in understanding and predicting the resistance encountered by fluids moving through conduits. These dimensionless parameters are essential in both ...

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 ...

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 ...

Many homeowners notice that plumbing noise becomes more prominent at night. Sounds such as knocking, ticking, banging, humming, or rushing water often seem louder when the building is quiet. While ...
