Special Issue Information

Dear Colleagues,

The study of ships and underwater vehicles is of great value to the oceanography field, with their movement dynamics being one of the key objects of study. The movement of ships and underwater vehicles involves transient and strong impacts, large deformations, movement instability, multiphase flows, structural damage, and other complex nonlinear mechanical difficulties, representing a great challenge for theoretical analysis, numerical computation, and experimental research.

This Special Issue is dedicated to research on the movement dynamics of ships and underwater vehicles. It will focus not only on the research methods and new technologies related to these vehicles’ movement dynamics but also on the mechanical characterization of complex multiphase flows, impact loading and structural responses, wave loading, near-free cavitation flow, and multi-vehicle interaction.

The potential value of the new type of vector propulsor in submarine movement has been confirmed. However, some key mechanical issues are not fully understood, especially the hydrodynamic characteristics during oblique motion. By using dynamic mesh simulation methods, a systematic study was conducted on the fluid dynamic behavior of pump-jet vector propulsor submarines during oblique and yawing processes, supplemented by the scientific validity of related experimental verification results. The research indicates that oblique movement causes a local stagnation positive pressure zone to form at the bow of the hull and a relative back pressure zone to form in the middle of the pump shell. As the angle of drift during oblique movement increases, significant improvements are observed in the lateral force, lateral velocity, and lateral moment of the submarine. During yawing motion, a negative pressure zone appears on the right side of the bow, with a local positive pressure zone appearing on the left side. In both oblique and yawing movements, the rotational speed has an amplifying effect on the appearance of the jet wake phenomenon for the submarine. Based on numerical results, a polynomial fitting method is used to establish a mathematical model for the variation in the speed coefficient and angular velocity system of the pump-jet vector propulsor submarine with the spiral mixed-flow pump speed. This study provides theoretical guidance for the application and optimization of pump-jet vector propulsors. Full article
