Dynamics Analysis of ADCP Carrier and its Mooring System

Abstract

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.
