Wang, L.; Guo, C.; Su, Y.; Wu, T., and Wang, S., 0000. Numerical study of viscous flow field mechanism for a non-geosim model. Inasmuch as the scale effect of wake fields has not yet been resolved, the application of a “Smart Dummy” model in predicting the full-scale nominal wake field and propeller-induced hull pressure fluctuations of ships sailing in coastal environments and zones farther out to sea has shown great potential since the concept was first proposed. However, it still has not been widely used because the rules and mechanisms of the Smart Dummy model are seldom studied by international and domestic researchers. A non-geometrically similar model (non-geosim model) of the KRISO3600TEU Container Ship (KCS) was designed by employing a local parameterization modeling method based on computational fluid dynamics numerical simulation methods. Based on the viscous flow field mechanism, numerical analysis was performed on the ship resistance performance, free-surface wave pattern, hull volum...
