“…Using Fluent software, flow field, drag size and flow field distribution about three different kinds of carriers were obtained [3]. Moreover, pressure distribution and drag coefficient CD of the three kinds of carriers could also be obtained [4,5]. The whole system was simplified to 12 discrete nodes, and attitude about mooring system was analyzed by Matlab.…”

Acoustic Doppler Current Profiler (ADCP) is one effective instrument to measure the sea current and is widely utilized in oceanographic research and ocean engineering. Some structure or frame is utilized to carry or hold ADCP in mooring system. This paper studies the hydrodynamics of different kinds of ADCP carriers and the motion of mooring system with ADCP carriers. By applying Fluent software external flow field of ADCP carrier is analyzed. Meanwhile, the velocity distribution and pressure distribution are obtained. Drag coefficients of ADCP carrier are used to analyze the mechanics and profile of mooring system with ADCP. Designing the ADCP carrier and mooring system is very useful which can provide theoretic basis for current data analysis.

In the Arctic, subglacial discharge plumes have been recently recognised as a key driver of fjord-scale circulation. However, owing to the danger that accompanies prolonged observations at plumes, no time-series data are available. Here, we present results showing the chaotic and irregular dynamics of a plume revealed by continuous subsurface monitoring directly on the calving front of a Greenlandic glacier. We found intense fluctuations in the current and scalars (temperature and salinity), recognised shallow and deep tidal modulation and anomalies due to co-seismic drainage of an ice-dammed lake via the plume, and observed rapid and marked changes in stratification. Our analysis uncovers energy cascade intermittency with coherent structures, corresponding to upwelling pulses of warm water. Prior to our research, in situ evidence of time-variable plume dynamics was absent and limited to snapshots, therefore, our study and approach will enable researchers to transition from an episodic view of a plume to a continuously updated image.

This article describes a literature review focused on published empirical measurements of external flows over bodies of revolution that can be employed for verification and validation of calculations of survey-class autonomous underwater vehicles (AUVs) or other like bodies. The flow regime for a survey-class AUV is defined, and a mathematically optimal velocity results for these energy-limited vehicles. A range-maximal hotel load is one of the inferences. Cavitation is shown not to affect this type of AUV. Environmental and computational problems of turbulence are discussed. A table of vital statistics of contemporary survey-class AUVs is provided.
