Abstract: An analytical expression for the discharge coefficient of ASME long-radius flow nozzles with zero beta ratio is presented. The latter condition corresponds to the installation of a metering ...

Abstract: Micro-inertia effects of surface roughness on hydrodynamic lubrication are analyzed in the light of similitude principles, viz. a newly conceived reduced Reynolds number and the classical parameter ...

Abstract: A numerical and experimental investigation of roughness effects on thin laminar fluid films is described. The flow considered is pressure driven in an essentially two-dimensional channel between a flat wall and a wavy one. ...

Abstract: The paper addresses the problem of unsteady flow in an elastic pipe, starting from rest and tending towards a turbulent steady state. Careful experiments, involving uncommonly long, smooth-walled conduits, indicate that ...

Abstract: The paper explores the time-wise evolution of selected turbulence parameters during gravity-driven flow establishment of incompressible fluids in rigid circular pipes. Two initial conditions are considered: flow starting ...

Abstract: A new analytical solution technique is presented which greatly extends the range of conduit shapes for which a mathematical description of the enclosed laminar flow becomes possible. To this end, a known particular solution

Abstract: Submergence of hydraulic jumps occurs frequently at low overflow structures, such as weirs and low‐head dams. In these cases the jump degenerates into a rotating current that produces a strong upstream‐directed surface ...
