ObjectiveThis study aims to investigate the influence and mechanism of a cup structure on the hydrodynamic performance of a surface-piercing propeller. MethodsBased on the RANS method and combined with the volume of fluid (VOF) and sliding mesh methods. a numerical simulation is carried out on an 841-B surface-piercing propeller with a cup structure modification under natural ventilat... https://allfixelectricales.shop/product-category/uhf-tv-antenna/
