Flow Field of XCP Probe's Head and Optimization Choice of Structural Parameters

Abstract

In this study, numerical simulation of XCP probe was executed. The 3D Navier-Stokes equations were used as governing equations, and the finite volume method combining two-equations turbulence model was applied. The flow field of XCP Probe was analyzed, especially around the XCP Probe's head. The results show that the arc design of the XCP Probe's head plays an important role on the steady falling speed. In addition, when the radian is 27°, the resistance of the probe is smallest and a larger falling speed can be achieved; The electrodes of probe should be located in front end of a conduit which is in the middle of the probe.

Analysis of and Reduction in Noise in Current Measurement of XCP under the Laboratory Condition

“…The systematic research on XCP in China began in the early 21st century, and many universities and research institutes carried out related research and exploration [12][13][14]. National Ocean Technology carried out a numerical simulation study on the flow field of the XCP probe during the descending process and optimized the XCP structure design [15][16][17]. At the same time, by building an experimental device and applying high time resolution TRPIV (Time Resolution Particle Image Velocimetry) technology, the two-dimensional instantaneous flow field and average flow field of the horizontal section of the XCP probe were measured, and the convective flow field at different rotational speeds and Reynolds number was analyzed.…”
