Overview

Examines how maneuverability conditions affect submerged water-jet performance and design implications.

Key Points

  • The aim is to analyze how maneuverability conditions impact the performance and flow characteristics of a submerged water-jet propulsor.
  • Performed both steady and unsteady numerical simulations.
  • Utilized an actuator disk model for unsteady analysis.
  • Analyzed entropy generation distribution among propulsor components.
  • Evaluated pressure fluctuations on the propulsor housing surface.
  • At a positive drift angle of 30°, propulsor head decreases by roughly 6%.
  • At a negative drift angle of 30°, propulsor head drops significantly by 28%.
  • Turbulent dissipation contributes 64% to the total entropy generation.
  • Optimal twin-jet spacing of 1.6D minimizes flow field interference.
