Self-propulsion simulation of DARPA suboff [PDF]
Hydrodynamic performance prediction of a propeller working behind a submerged body is a popular research field. For a submarine propeller, the propeller-hull interaction should be considered during the preliminary design stage. In this study, the resistance and propulsion analyses of the well-known bench-mark DARPA Suboff with E1619 propeller have been

Computational investigation of the self propulsıon performance of Darpa Suboff vehicle [PDF]
In this paper, the resistance and power values which are very important for the hydrodynamic performance of an underwater vehicle have been calculated using both an empirical method and Computational Fluid Dynamics (CFD) analysis. The self-propulsion of the vehicle has been investigated using Actuator Disk Theory.
