Abstract
We introduce a computational method for designing minimum-drag galvanic anodes for tunnel thrusters, assuming a given maximum anode mold diameter and a given anode weight. The method is illustrated for a tunnel of 1000 mm radius, and the results are evaluated by using Computational Fluid Dynamics (CFD). For a representative 45° tunnel flow, the pressure drop caused by a single anode can be reduced by 92% and the risk of cavitation mitigated relative to a rectangular block anode shape
