Tittel

Experimental and Numerical Investigation of Open Thrusters in Oblique Flow Conditions

Sammendrag

In order to obtain insight into the hydrodynamic loadings including steering moment of open thrusters, numerical investigations and model tests of open thrusters were performed. Tests were performed under both positive and negative advance speeds. Azimuth angles –90 to +90 degrees were investigated. Wireless transmission was used to minimize data transfer noise. The objective of the study was to help to understand the effect of oblique flow (azimuth angle) on hydrodynamic loadings of open thrusters (as well as pods) which in turn can improve the design of thrusters for realistic loads. In addition test results deliver crucial information required for better management of different dynamic positioning scenarios. Numerical methods and experimental test setup are described. Measurements of propeller thrust and torque, total thrust, side force and steering moment at different azimuth angles and at different advance coefficients are presented and discussed. Numerical analysis results together with their experimental verifications are presented and discussed.
