The results for both the OWC and BHC show that the propeller thrust and torque vary significantly with angles of incidence; the BHC having the greatest variation. A greater inflow angle produces more noticeable in-plane loads on the propeller, which will cause a moment that acts to reduce the drift angle of the vessel during manoeuvres.
This work contributes to the understanding of the effect of inflow angles on the propulsion properties of submarine propellers and the development of representative body force propellers. The latter are often used in place of rotating propellers for CFD based free running submarine manoeuvring simulations, thus significantly reducing computational cost.
