An Experimental Study of Bivalve Siphonal Jets in a Turbulent Boundary Layer Crossflow
We conducted experiments in a laboratory flume to study the interaction of bivalve siphonal jets with the turbulent boundary layer which forms in the benthic region of shallow estuaries....
Hydraulic Modeling of High Unit Discharge Energy Dissipators
The incorporation of an efficient and economical energy dissipation device is critical with respect to the safe operation of a high unit discharge spillway. The development and design...
Integration of Environmental Management with Reservoir and Power System Operations
Two examples related to the Tennessee Valley Authority's reservoir and power systems operation with environmental performance and management as major goals are given in this paper. One...
Design of a Curved Baffle Energy Dissipation Structure
A curved baffle energy dissipation structure was designed and constructed based on the results of hydraulic and analytical models. Field tests of the prototype demonstrate close comparison...
Measurement of Bridge Scour at the SR-32 Crossing of the Sacramento River at Hamilton City, California, 1987-92
A study of the State Route 32 crossing of the Sacramento River near Hamilton City, California, is being made to determine those channel and bridge factors that contribute to scour at the...
Recent Developments in Safety Research from the Gas Research Institute
Recent developments in Safety Research, as supported by the Gas Research Institute (GRI), have consisted primarily of hardware-oriented applications to various gas industry safety operations....
The Transrapid EMS Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application. The maglev system uses contactless electromagnetic suspension and three...
Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...
Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
Regeneration?Potentially Powerful Stuff
Virtually all Automated People Movers (APMs) use electrical power for propulsion. Many designs also use electrical braking to augment any mechanical braking devices for decelerating trains....
Reinforced Concrete
Recent developments and procedures used to model reinforced concrete using finite element analysis are summarized. Special emphasis is placed on the results of a survey of papers published...
Engineering Sustainable Development
Despite some isolated environmental victories in the past few decades, on a system-wide level the problems�from acid rain to destruction of the rain forest�are getting worse. Can humanity...
Compendium of Pumped Storage Plants in the United States
The
Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...
Venezuela Turns to Port
Despite Venezuela's recent political troubles, geography and economics argue for a big increase in the country's port capacity. Oil has traditionally been the...
Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...
Energy Dissipation Characteristics of Rubber Cylinders
A simplified procedure for scaling the energy absorption characteristics of rubber cylinders during high speed impact is presented. Static and dynamic tests of scale model and full size...
Turbulence, and Energy Loss, at Combining Pipe Junctions
Efforts to measure and describe the loss of energy at 90? sharp-edged junctions are described. The work is focussed on energy losses at discharge and area ratios for which there are no...
Variational Solutions of the Von Karman Plate Theory Based on a Mixed Formulation
A mixed formulation, involving the transverse deflection w(x,y) and the in-plane stress function F(x,y) as the unknown variables, will be used to obtain improved variational solutions...
Regularization Methods for Identification of Structural Damage
Generally, various non-unique solutions may be obtained from ill-conditioned equations. Several methods are available to obtain a unique (minimum energy) solution to a modified and thus...
