Study on the Prediction of the SWATH Resistance Taking the Effect of Sinkage and Trim into Account

摘要

The numerical simulation of SWATH 3D flow field was carried out based on VOF model. The sinkage and trim were gained in the static balance equation after calculating the surface pressure distribution of SWATH in designed upright state. The iterative calculation of the prediction for SWATH was made by changing the navigation state. The total resistance prediction of SWATH model agrees well with the experimental date taking the effect of sinkage and trim into account.
