The subject of the presented research project is the exact knowledge about the parameters influencing the operating characteristics and limiting the maximum power of low pressure hydraulic vane type machines, used as drives for ship-deck machinery, to obtain a full utilisation of the potential of these motor type, and the intera ction between biodegradable hydraulic fluids and hydrostatic units...

This paper presents an investigation of the hydro elastic behavior of vibrating blades in hydraulic machines, which is of strong interest for turbo machinery applications. As a representative case study for vibrating blade in hydraulic machines, a NACA 0009 oscillating hydrofoil is considered. The aim is to model the hydrodynamic moment acting on the oscillating hydrofoil. Two types of oscillat...

I propose to consider the question, “Can machines think?” This should begin with definitions of the meaning of the terms “machine” and “think.” The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words“machine”and “think” are to be found by examining how they are commonly used it is difficult to e...

As one of the typical negative factors affecting vortex structure and flow characteristics hydraulic machinery, TLV has a non-negligible impact on energy performance. In order to improve utilization efficiency machinery in marine energy, parallel grooves is proposed applied NACA0009 hydrofoil. Subsequently, an exhaustive numerical analysis carried out adopting SST k-ω turbulence model, effects ...

INTRODUCTION The majority (67%) of hospitalized injuries among Alaska commercial fishermen are associated with deck machinery. This paper describes the "Prevention Through Design" process to mitigate one serious machinery entanglement hazard posed by a capstan deck winch. METHODS After observing that the capstan winch provides no entanglement protection and the hydraulic controls are usually ...
