Power Flow Calculation Method of Large Shipboard Power System
power flow method node voltage method asynchronous motor transformer
2011/9/9
The effect of line voltage drop is considered larger on loads, especially on asynchronous motor, transformers and other non-linear load parameters in power system of large ships. A novel power flow me...
Surface flow structure of the Gulf Stream from composite imagery and satellite-tracked drifters
Surface flow structure Gulf Stream composite imagery satellite-tracked drifters
2009/11/16
A unique set of coutemporaneous satellite-tracked drifters and five-day composite Advanced Very High Resolution Radionmeter (AVHRR) satellite imagery of the North Atlantic has been analyzed to examine...
Thermohaline Structure and Baroclinic Flow Across the Gulf of California Entrance and in the Revilla Gigedo Islands Region
Thermohaline Structure Gulf of California Entrance Baroclinic Flow Revilla Gigedo Islands Region
2009/4/3
The thermohaline structure, vertical stability and baroclinic flow between the Gulf of California entrance and the Revilla Gigedo islands are investigated by means of closely spaced salinity and tempe...
The Structure of the Residual Flow in an Offshore Tidal Stream
Residual Flow an Offshore Tidal Stream
2009/4/3
A theoretical account is given of the turbulent boundary layer at the ocean floor beneath a co-oscillating tidal flow. A parameterization, involving the techniques described by Johns and Dyke, is used...
The Samoan Passage at about 10S, 169W appears to be the major channel through which the deep and abyssal waters flow northward from the South Pacific. The northward flow, Postulated from the distribut...
The Flow of a Two-Layer Fluid over Topography in a Polar Ocean
Two-Layer Fluid Topography Polar Ocean
2009/3/24
A two-layer model is constructed for wind-driven flow over topography in a closed polar basin where the variation of Coriolis force with latitude is negligible. The model equations are reduced using s...
Measurements of Wind-Driven Flow Profiles in the Top Millimeter of Water
Wind-Driven Flow Profiles Top Millimeter
2009/3/24
Shapes of mean water velocity profiles measured with microscopic bubble tracers in developing, laminar flows are recognizably different from those in a turbulent flow. A previously deduced viscous sub...
The Noutidal Flow in the Providence River of Narragansett Bay：A Stochastic Approach to Estuarine Circulation
Noutidal Flow Narragansett Bay Providence River Estuarine Circulation
2009/3/7
Atmospherically driven flow in the Providence River (a partially mixed estuary) has been examined using a 51-day velocity record measured 2 m from the bottom. Velocity fluctuations at time scales betw...
On the Flow Through Barrow Canyon
Barrow Canyon Simultaneous current temperature measurements
2009/3/7
Simultaneous current and temperature measurements were made at two depths in Barrow Canyon for a period of 120 days from April through August, 1973. The mean of the measured currents was 25 cm s−...
Water Volume Transport and Oscillatory Current Flow through the Straits of Mackinac
Water Volume Transport Mackinac Oscillatory Current Flow
2009/3/7
Currents flowing through the Straits of Mackinac were recorded for a period of nearly 100 days during the summer and fall of 1973. Current meters were placed at four moorings on a north–south cross se...
Variability of Deep Flow in the Drake Passage from Year-Long Current Measurements
Deep Flow Year-Long Current Measurements Drake Passage
2009/3/7
To investigate the reasons for the wide variation in previous estimates of transport of the Antarctic Circumpolar Current through the Drake Passage, an analysis of the spatial and temporal variability...
Residual Flow and Boundary Shear Stress in the Turbulent Bottom Layer Beneath Waves
Residual Flow Turbulent Bottom Layer Beneath Waves
2009/3/7
A model is considered of the turbulent bottom boundary layer beneath waves. Closure is effected at the level of the turbulent energy equation and numerical solutions are obtained by a combination of f...
