Computational Analysis of Propeller Sheet Cavitation and Propeller-ship Interaction

This paper describes a computational procedure which is being developed for the practical analysis of propeller sheet cavitation and propeller-ship interaction including hull pressure fluctuations. The computational procedure consists of three different, coupled methods: (i) a RANS method for the analysis of the viscous flow around the ship hull and the determination of the velocity field in th...

Cavitation Tunnel Tests for Propeller Noise of a Frv and Comparisons with Full-scale Measurements

This study presents the results of cavitation tunnel tests carried out with model propeller of a Fisheries Research Vessel (FRV) and those of noise measurements with its full-scale propeller to validate the low-noise performance of this propeller. The tests involve the simulation of a target wake using a wake screen and the determination of the nature and extent of the observed cavitation behin...

Employment of Wireless Sensor Networks for Full-Scale Ship Application

In this study, basic experiments regarding the wireless sensor network were conducted on a 3,000-ton-class training ship as the first step in applying the ubiquitous technology to a real ship. Various application fields of the technology in terms of the provision of safety and convenience on a ship would be extracted through these experiments. To efficiently adopt the ubiquitous technology for ...

Numerical Simulation of an Ultrasonic Vibratory Cavitation Device

As an experimental quantitative method to assess erosion risk, the acoustic emission (AE) technique has been employed, for example, by Lloyds Register for more than a decade now to complement their borescopic cavitation observation at the ship scale. Boorsma and Fitzsimmons (2009) reported (see Fig. 1,) its correlation with borescope observed cavitation events appeared very positive and the loc...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
