A Semi-Empirical Model for an OC-OTEC Spout Flash Evaporator
A phenomenological model for the thermal-hydraulics of a spout flash evaporator is presented in this paper. The model considers the two-phase flow behavior both in the spout and in the...

OTEC Sea Water Systems Technology Status
A workshop was conducted in April 1988 to provide an expert critique of the fabrication and deployment options for the seawater systems (all piping required to draw the seawater) of land-based...

OTEC Seawater Pipe Cost Comparisons
Describes a material which can substantially reduce the cost of seawater pipes and two methods for building and deploying such pipes for use in land-based OTEC installations, outfall sewers,...

Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...

Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...

De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...

Experimental Investigation of Condensation of Steam in the Presence of Noncondensable Gases for Open-Cycle Surface Condensers
Two experimental investigations are being carried out for determination of the effects of noncondensable gases on the rate of condensation in the open-cycle surface condenser. A single-channel...

Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO2 release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...

Long-Term Performance Reliability of Wood Materials
The United States faces a major task in maintaining and rebuilding the nation's infrastructure in the 1990's and beyond. Economic constraints have limited funds...

Practical Prediction of Concrete Shrinkage and its Uncertainty
An improved prediction model for shrinkage is proposed. The main features are (1) diffusion-type size dependence for humidity effects, (2) initial and final asymptotic forms of the shrinkage...

Selected Earthquake Engineering Papers of George W. Housner
Sponsored by the Structural Division of ASCE. This volume collects key papers on earthquake engineering by George W. Housner, who more than any other...

Gateways to Understanding
Automating engineering design processes are crucial to the growth and the very survival of professional services providers. The need to enhance their competitiveness and the value provided...

Ocean Energy Recovery
This proceeding of the International Conference on Ocean Energy Recovery held in Honolulu, Hawaii from November 28-30, 1989 consists of thirty-eight papers. These papers explore various...

Earthquake Research Needs for Nuclear Power Plants
Originally published in: Journal of the Power Division, ASCE, PO1, January 1971, pp. 77-91...

Fired Up at Fort Drum
The U.S. Army's first major privatization contract was signed for design, construction, operation and ownership of the Fort Drum powerplant at the newly constructed base for...

An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...

Transmission Line Structure Loading
This paper outlines specific procedures for determining loads on transmission line structure systems that can be used in the reliability based design or assessment of components of these...

Improved Techniques for Assessing Structures
The Electric Power Research Institute (EPRI) has specially designed and equipped the tower testing station located within their Transmission Line Mechanical Research Center (TLMRC) near...

Assessment of Conductors
This paper deals with the mechanical integrity of conductors after several years in service and discusses current innovative conductor designs which benefit the structural designer working...

Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...
