| Abstract: | The flow characteristics of protrusions and holes on a submerged body are studied by solving the RANS equations.Detailed flow structures and resistances of body with protrusions and holes are presented.The results show that they have a notable influence on resistance and flow field.So the protrusions and holes should be made a optimizations of design. |
