Modeling and Simulation of the Bollard Pull Test on Twin Propeller Tugboats using CFD

摘要

A finite volume model had been developed to simulate the bollard pull test of twin propeller tugboats. The Navier-Stokes equations are solved by using ANSYS FLUENT along with the Reynolds Averaged Navier- Stokes and the SST k-w turbulence model. A study is carried out under the standard test conditions using steady and transient methods. In addition, a study is presented for situations where the test environment cannot comply with the ideal conditions of the test. Thus, the effect of dimensions of the test channel was considered. A validation of the results by comparing with experimental and theoretical data was made with excellent agreement.
