Operation of the Annapolis Tidal Straflo Unit
The Annapolis Tidal Generating Station, located at Annapolis Royal, Nova Scotia, is the first plant in North America to generate electricity by Tidal action. The facility, rated at 19....
A New Turgo Turbine in China
In this paper a special runner bucket of the new Turgo turbine is illustrated and a comparison is made between the characteristics of the new Turgo and the ordinary Turgo turbine with...
Rim-Drive Turbine for Low Head Applications
A turbine design and testing program was undertaken with the objective of developing a standardized turbine/generator arrangement that would be well suited to the 10 to 30 foot head range....
Economic Analysis of Low Head Hydropower Projects
A typical low head hydropower project is described and used as an example of the effect of tailwater on power generation. The discharge characteristics of upstream facilities, pool regulation...
The PowerBarge?Portable Hydro for the Third World
The PowerBarge concept consists of a floating intake, siphon penstock, and floating generating station for use at new or existing low-head dams. Apart from access, mooring facilities,...
Optimization of Low Head Hydro Equipment
In this paper, we will limit our purpose to the presentation of the different types of turbines that CE/Neyrpic proposes for low head power plants, for run of the river operations. We...
Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
Finite Element Discretization for Mixed-Mode Fracture Problems
The finite element discretization of mixed-mode problems in fracture mechanics is investigated. The characteristics of the mesh near the crack affect the accuracy of the finite element...
Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...
Improved Method for the Dynamic Response of Bilinear Systems
A procedure is presented to eliminate the error introduced in the step-by-step numerical integration of the equations of motion of hysteretic bilinear systems subjected to earthquake excitations...
Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...
Interactive CAL Modules for Mechanics of Solids
Traditionally the basic engineering course in 'Mechanics of Solids' has proven to be a challenge to both the students and faculty, for although the fundamental...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Mechanics of Crack Propagation in Stiff Clays
Many stiff clays forming part of natural slopes and earth dams exist in the fissured state. When these cracks are subjected to gravity induced normal and shear stresses they may propagate....
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
