Special Issue Information

Dear Colleagues,

Marine fluid machinery and systems have been widely used in marine engineering such as seabed exploration, exploitation of marine resources and laying of submarine pipelines, etc. At present, the complexity of application scenarios has put forward higher demands for the accuracy, efficiency, reliability, and intelligence of the marine fluid machinery and systems.

Thus, how to achieve and maintain the high performance of the marine fluid machinery and systems during their whole service life is an unending pursuit. The growing demands to increase of processes’ operation efficiency have encouraged optimization at the design stages for marine fluid machinery and systems based on hydraulic modeling, numerical simulation, or data-driven techniques.

This Special Issue on “Hydraulic Modeling, Optimization and Intelligent Maintenance of Marine Fluid Machinery and Systems” seeks high-quality works focusing on the latest novel advances regarding the modeling, simulation, optimization, controlling, application, and maintenance of all kinds of marine fluid machinery and systems such as tidal turbines, underwater robots, water-jet pump and propellers, etc. The topics within the scope of the issue are mainly the following, but are not limited to this:

  1. Modeling and simulation of marine fluid machinery and system;
  2. Design and optimization of marine fluid component and system;
  3. Advanced control strategy for unsteady flows or instabilities;
  4. Fault diagnosis and life prediction of marine fluid component and system;
  5. Intelligent maintenance of marine fluid machinery and system;
  6. Advanced applications of marine fluid machinery and system.

In this paper, the hydrodynamic characteristics of a rim-driven thruster (RDT) behind the hull of an underwater vehicle are investigated. The studied underwater vehicle is the benchmark DARPA (Defense Advanced Research Projects Agency) suboff model, with and without full appendages. In order to verify and validate the numerical model, a grid sensitivity analysis is made for the AFF-1, AFF-8 and the ducted propeller cases, respectively. Then, the resistance and pressure distribution over the surface of the suboff with and without appendages are compared with available experimental measurements and good correlations were observed. As for the propeller, a well-studied ducted propeller, the 19A duct in combination with Ka-47 blades, is employed, and the numerical results exhibit a close relationship with the available experimental data under a wide range of advance coefficients. Afterwards, the self-propulsion characteristics of the suboff models propelled by RDTs using different duct configurations are studied, more specifically, the unsteady effects of the flow field induced by the interactions between propeller and hull under various working conditions. The results indicate that due to the influence of the hull, the RDTs operate in different working conditions compared to open water and exhibit distinct hydrodynamic characteristics. Moreover, the duct profile can have a significant effect on the unsteady pressure fluctuations in the flow field, especially in the vicinity of the propeller. Full article

The dual-input single-output (DI-SO) cylindrical spur gear system possesses advantages such as high load-carrying capacity, precise transmission, and low energy loss. It is increasingly becoming a core component of power transmission systems in maritime vessels, aerospace, marine engineering, and construction machinery. In practical operation, the stability of the DI-SO cylindrical spur gear system is influenced by complex excitations. These excitations lead to nonlinear vibration, meshing instability, and noise, which affect the performance and reliability of the entire equipment. Hence, the dynamic performance of the DI-SO cylindrical spur gear system is thoroughly investigated in this research. The impact of excitations and nonlinear factors on the dynamic characteristics was investigated comprehensively. A comparative analysis of the gear system was conducted by establishing a bending–torsional coupling vibration analysis model under synchronous and asynchronous meshing conditions. Nonlinear factors such as periodic time-varying meshing stiffness, meshing damping, friction coefficient, friction arms, load sharing ratio, comprehensive transmission error, and backlash were considered in the proposed model. Then, the effect laws of excitations and nonlinear factors such as meshing frequency, driving load fluctuation, backlash, and comprehensive transmission error were analyzed. The results indicate that the dynamic characteristics exhibited staged stable and unstable states under different meshing frequencies and meshing conditions. At the medium-frequency meshing stage (0.96 × 104~1.78 × 104 Hz), alternating phenomena of multi-periodic, quasi-periodic, and chaotic motion states were observed. Moreover, the root mean square value (RMS) of the dynamic transmission error (DTE) in the asynchronized gear system was generally higher than that in the synchronized gear system. It was found that selecting the appropriate meshing condition could effectively reduce the amplitude of the DTE. Additionally, the dynamic performance could be significantly improved by adjusting control parameters such as driving load fluctuation (0~179 N), backlash (0.8 × 10−4~0.9 × 10−4 m), and comprehensive transmission error (7.9 × 10−4~9.4 × 10−4 m). The research results provide a theoretical guidance for the design and optimization of the DI-SO cylindrical spur gear system. Full article
