Abstract:

Transverse thrusters are widely used in ships and offshore platforms with high maneuverability requirements， such as those marine structures with tasks of port operation， scientific research， rescue and marine resources development. The research progress related to the tunnel thruster are reviewed， which include the hydrodynamic performance prediction method， propeller design， resistance and noise reduction design of flow entrance， factors influencing work capability， cavitation， noise， fluctuating pressure， roll reduction and maneuverability effect. The factors influencing the work capability of tunnel thruster are summarized in details and subdivided into tunnel mouth shape， internal flow field， ship speed and Coanda effect， tunnel and hull shape， the hydrodynamic interactions between tunnel thruster and other thrusters， free surface and restricted channel. At last， the further development on the hydrodynamic performance of tunnel thruster are analyzed and prospected.
