Pressure Fluctuations in Reattaching Flow
Wall-pressure fluctuations are measured behind a plate fixed normal to the wall, and spanning the test section of a water tunnel. Two plates are used, the ratios of their heights to the...

Laminar Flow Between Rotating Porous Disks
A perturbation solution of the equations of motion for steady, incompressible, laminar flow between a porous rotating disk and a stationary nonporous disk has been obtained. The solution...

Slow Ono-Newtonian Flow in a Zone of Separation
Slow motions of purely viscous fluids in a two-dimensional conduit expansion are investigated using a finite-difference numerical scheme. The important concepts in the general theory leading...

Generalized Profiles of Gradually Varied Flow
A pattern of similarity is established by means of analytical and dimensional analyses in the nondimensional forms of water-surface profiles of gradually varied flow on mild and steep...

Horizontal Two-Dimensional Density Current
The flow in the region of entrainment for a two dimensional horizontal density current was examined and was compared with that of the hydraulic jump, it has been shown that the depth of...

Flow in a Sharp Corner
The flow in a V-shaped open channel is studied in the Reynolds number regime where laminar and turbulent flow can coexist. The narrow corner produces a relatively thick laminar sublayer...

Laminar Flow Between Porous Disks
The equation of motion for steady, incompressible, axially symmetric flow between parallel porous disks have been solved. The flow is entirely the result of either suction or injection...

Stokes Flow Behavior of an Accelerating Sphere
The relation for the force on a sphere undergoing an arbitrary rectilinear acceleration in a viscous fluid was established by Basset in the late nineteenth century. His derivation is based...

Characteristics on M1 Backwater Curves
An analysis of M1 profiles with Froude number as a reference parameter is made. A total of 182 M1 profiles in rectangular, trapezoidal, triangular, and parabolic channels are studied....

Experiments on Lateral Dispersion in Porous Media
Experiments are carried out to determine the coefficient, D, of lateral dispersion in flow through porous media, with values of R between 0.3...

Flow Direction Measurement by Hot-Wire Anemometry
The theory of forced convection caused by the normal and the longitudinal components off the flow around a hot-wire is reviewed. The effect of wire length and the corresponding corrections...

Wind Driven Water Currents
Flow induced in a body of water by wind blowing over the surface is studied in a series of experiments in a laboratory channel. Results are coordinated by dimensional analysis and general...

Turbulent Flow in a Three-Dimensional Channel
The results of tests to define the Reynolds stress tensor in one corner of a straight, smooth, closed conduit of rectangular cross section were presented. The measurements are used in...

Sediment Transport in Supercritical Flow
A study is made of the transition between flow of a solids-fluid mixture in the fully suspended regime and flow with a sediment bed. It is shown that the critical deposit condition is...

On Froude-Cauchy Similitude

Hydraulic Jump in All Shapes of Horizontal Channels
A simple analytical solution is presented of the ratios of conjugate depth and energy loss in terms of the upstream Froude number for the hydraulic jump in horizontal rectangular, triangular,...

Accelerated Motion of a Sphere in a Viscous Fluid
An investigation was made of the free fall of a sphere from rest in a viscous fluid in order to gain a better understanding of this fundamental form of accelerated motion. For spheres...

Resistance of Cylindrical Piers in Open-Channel Flow
An experimental investigation of the variation of the resistance coefficient of cylindrical piers in a rectangular channel was conducted. The resistance coefficient was determined as a...

Characteristics of the Backwater Curve
The profiles of over forty Ml curves in rectangular channels are examined. The ranges of variables covered are: n, from 0.012 to 0.050; breadth-to-depth ratio, 2, 10, and infinity; and...

Dispersion and Adsorption in Porous Media Flow
A mathematical analysis is presented of the phenomenon of simultaneous dispersion and adsorption of a solute in porous media flow. Mathematical solutions are given that refer to the case...
