Development and Methods on Theoretical Research of Marine Propellers

Combined with three stages of theoretical research on marine propellers in recent years, the development of research methods for marine propeller theories was reviewed and briefly analyzed. Mo-mentum theory, blade element theory, lifting lines theory, lifting surface theory and boundary element method were introduced respectively. The relationship between propeller theories and hydrodynamics was discussed primarily. The application on computational fluid dynamics of viscous fluid dynamics method was stresse...
