Building a Marina in Mexico
The objective of this paper is to present a summary of the development of marinas in Mexico, especially in the last five years, since the relaxation of government regulations in this sphere,...

Licensee Tort Liability and Regulatory Overreaching
Certain of the Federal Energy Regulatory Commission's (FERC) regulations and licensing requirements effectively preempt the states' authority to determine liability....

Drag Characteristics of Spheres in Bingham Fluids
R.W. Ansley and T.N. Smith's type of drag relation can be traced back closely, if not completely, to the Newtonian drag curve. The equivalent diameter for a sphere in a Bingham...

Experiments on the Gravity-Free Dispersion of Large Solid Spheres in a Newtonian Fluid under Shear (1954)

Comparing Coastal Spheres in Oregon and Washington
This paper introduces the concept of a 'coastal sphere' and illustrates its use by applying it to two such spheres located in the Pacific Northwest. A sphere...

Low Velocity Impact Resistance of Tough Composites

Size Gradation and Stresses in Rapid Granular Flows

Effect of Pressure Gradient on the Motion of a Sphere in an Oscillating Fluid

A Survey of Methods to Measure Vorticity in Turbulent Flows

Stresses on Rapidly Sheared Fluid-Solid Mixtures
Constitutive equations were derived describing the stress in a rapidly sheared mixture of granular cohesionless solids and a Newtonian fluid. These equations are considered to describe...

Compliance of Assemblage of Unlike Elastic Spheres
An investigation is made of the load-response behavior of a simple granular cell consisting of the following: two like elastic spheres separated at zero load by a ring of restrained smaller...

Settling Velocity of Spherical Particles in Calm Water
The settling velocities of round and smooth spherical particles in calm water at 200 /LT R /LT 6,000 were analysed utilizing modern measuring techniques. When the present results are compared...

Expanded Polystyrene Spheres as Evaporation Suppressors
Tests were made both under indoor and outdoor conditions, land and floating pans covered with beads to produce various water surface coverage. Daily measurements of evaporation and water...

Added Mass of Sphere near Floor in Oscillatory Waves
The purpose of this note is to examine how the added mass of a fixed submerged sphere changes in the presence of a free surface (in addition to the wall boundary at the bottom) in two-dimensional...

Nonlinear Inertia Forces on Bodies
The theoretical influence of convective acceleration terms on the inertia force on a body is considered. The assumptions involved in using the inertia force are reviewed and an expression...

Effect of Free-Stream Turbulence on Drag of Bluff Bodies

Further Tests on Ocean Wave Forces on Sphere
Wave force coefficients have been obtained for a 28.8-in diam sphere. The work was done at a test site in 37 ft of water offshore from Honolulu. The peak flow velocities encountered during...

Scour of Bed Material in Very Rough Channels
Experiments with densely packed uniform spheres have confirmed that the initiation of motion of bed material is affected by the relative roughness of the channel. At shallow depths, larger...

Experiments on Surface Buoyant Jet
An experimental investigation of a surface buoyant jet is presented. The densimetric Froude number and the Reynolds number of the discharge channel were 3.6 and 33,000, respectively. Longitudinal...

Fluid Dynamic Lift on a Bed Particle
Direct measurement of lift forces acting on an exposed sphere at the boundary of a fluid flow shows that the lift force may be negative (i.e., directed toward the boundary) if the grain-size...
