Abstract: Frictional pressure drop in rectangular ducts is examined. Using correspondence between theory and experiment in laminar flow as a means for acceptance of published data, turbulent flow data for ...

Abstract: Data for smooth concentric annuli having an overall −25 to +35 percent scattter about the Colbrook prediction for smooth tubes, along with calculation techniques, are reviewed. It is shown that ...

Abstract: An extension of the k-ε model for bubbly two-phase flow is proposed and tested against experimental data. The basic assumption made is that the shear-induced turbulence and bubble-induced ...

Abstract: A small segment of the engineering community was surveyed to obtain their judgment regarding the long-range needs for basic research in fluid mechanics. This segment consisted of approximately ...

Abstract: The statistical characteristics of turbulent two-phase pipe flow have been evaluated. In particular, the autocorrelation functions and the power spectral density functions of the axial turbulence ...
