First- and Second-Law Analysis of Steam-Turbine Cogeneration Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents an analysis of a cogeneration plant. The performance of the plant is compared to a conventional plant with separate production of process heat and power. The analysis is ...
Velocity Characteristics of a Confined Coaxial Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The velocity characteristics of a turbulent, confined, coaxial-jet flow have been determined by measurement and by the solution of conservation equations in differential form. The ratios of maximum ...
Velocity Characteristics of Confined Coaxial Jets With and Without Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measured values of the velocity characteristics of turbulent, confined, coaxial-jet flows have been obtained, without swirl, for ratios of maximum annulus to pipe velocities of 1.0 and 3.0 and ...
Calculation of Turbulent Flow and Heat Transfer in Channels With Streamwise-Periodic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational method for the calculation of the flow and heat transfer in a channel, with elements of various heights inducing a streamwise-periodic flow, is presented and evaluated. The ...
Acoustic Detection of Leaks in Water Pipelines Using Measurements inside Pipe
Publisher: American Society of Civil Engineers
Abstract: Acoustic leak-detection techniques are proven to be effective and have been widely used in water-distribution systems for several decades. Most of the existing acoustic leak-detection techniques rely on external measurements ...
On the Development of Deadleg Criterion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Corrosion in deadlegs occurs as a result of water separation due to the very low flow velocity. This work aims to investigate the effect of geometry and orientation on flow field and oil/water ...
Influence of Boiler Load Swing Rates on Effective Stresses of Drum Boiler Riser Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, different rates of steam flow (swing rates) are used to demonstrate the transient changes in both the drum-boiler steam pressure and the wall temperature levels in addition to ...
