PROPELLER-HULL INTERACTION IN INLAND NAVIGATION VESSEL

The author presents a computational model of a propeller operating in the wake of an inland navigation flat-bottomed vessel. Using this model it is possible to compute propeller performance as well as propeller-hull interaction coefficients (wake fraction and thrust deduction factor) with limited depth of waterway taken into account. The surface distribution technique was applied to solve the flow over the nozzle (part of a ducted propeller) and a potential component of the flow between the hull and waterway bottom. A vortex lattice model was used for a screw propeller or impeller. A simplified Reynolds equation was solved to determine axial velocity in the flow domain. Results of the calculations showed good agreement with available results of model tests.
