This paper investigates the influence of the propeller race on upstream and downstream self-propelled AUVs. Initially simulations of a self-propelled hull are performed at the Reynolds Number 3.2×106 with the commercial RANS code ANSYS CFX 12.1, utilising a body force model to replicate the impact of the propeller utilising momentum source terms. This is then extended to consider a fleet of two self-propelled...
This paper investigates the influence on the fleet of the drag of multiple towed prolate spheroids to determine the hydrodynamic effect of the viscous interaction between hulls and to study the influence of the configuration׳s shape of multiple hulls in the vee and echelon formations. A series of CFD RANS-SST simulations has been performed at the Reynolds Number 3.2×10 6 by a commercial code...
