RANS Computations of Added Resistance of Advancing Modified Wigley Ships in Head Waves

摘要

In this paper, RANS simulations on added resistances and verticalrnmotions of modified Wigley ship advancing in head waves with arnFroude number of 0.2 are presented. The numerical computations arernfulfilled by our in-house solver naoe-FOAM-SJTU based on openrnsource package OpenFOAM. Regular wave conditions with a widernrange of wave length (0.4<λ/L<1.6) are considered besides the steadyrncalm-water cases. The simulations are compared very well with thosernusing unsteady wave analysis methods. Good agreement withrnexperimental measurement is also observed. It shows that the solverrnnaoe-FOAM-SJTU has good potential to study more complex addedrnresistance issues.
