Thrust vector control by scarfed nozzle jet can realize attitude control and trajectory adjustment of the undersea vehicle and improve the maneuvering performance and stability of the undersea vehicle. In order to investigate the working state of the underwater scarfed nozzle. the Reynolds time-averaged Navier-Stokes(RANS) method and the volume of fluid(VOF) model were used. and simul... https://www.roneverhart.com/2-1-2-x-1-4-x-36-Smooth-Saddle-Threshold-NGP-410-36/
