Inland vessels have more complex rudder configurations than seagoing ships. Currently, the rudder profile, the number of rudders, and the spacing between rudders are not considered in the empirical methods for rudder force calculation. To analyze the impacts of the rudder configurations on inland vessel maneuverability, the hydrodynamic characteristics, for instance, lift and drag coefficients, of each configuration need to be calculated specifically. Conventional methods to study rudder hydrodynamics are wind-tunnel and open water tests. Due to the high cost and the scale effects of the model tests, the Computational Fluid Dynamics (CFD) method is considered as an increasingly attractive alternative. CFD methods are roughly classed in a hierarchy of lifting-line, boundary element, Reynolds-Averaged Navier–Stokes (RANS), Large Eddy Simulation (LES), and Direct Numerical Simulation (DNS) methods.
