| Popis: | A technique for studying the effectiveness of bow thrusters of the "propeller in a tunnel" type is proposed, validated, and checked by testing models in a hydrodynamic tunnel. The interaction of the thruster generated jets with the flow near a ship hull model is studied at low flow velocities. The dependence of the lateral force on the shape of the initial cross section and the relative velocity of the jet outflowing from the thruster tunnel is studied. A strong dependence of the lateral force on the Reynolds number based on the free-stream velocity and the characteristic dimension of the initial jet section is revealed on the range of relative jet velocities investigated. The case of cavitation collision of the thruster jet with the external flow, when a considerable amount of gas is fed into the near wake zone downstream of the jet, is also examined. |
