Verification and Validation Study of Computational Fluid Dynamics for KCS Container Ship Resistance Result Using Shear Stress Transport Turbulence Model

One of the important issues in evaluating the numerical analysis of ship resistance by the computational fluid dynamics method is to investigate its uncertainty, which includes verification and validation studies. In this study, the KCS container Ship in calm water was simulated numerically at the design speed, equivalent of Froude number 0.26. The finite volume method was used to discretize the Navier Stokes equations and the turbulence model of shear stress transfer. The free surface was modeled by the fluid volume and inertia of the ship motions using the coupled rigid-body coupling equations with fluid. Uncertainty values were assessed for verification and validation studies. The verification study was investigated by three simulation solutions with different mesh resolution . The numerical method uncertainty was less than 5.76% after the study and in the validation study, considering the uncertainty of the model test, the uncertainty was 5.84%. The results showed good accuracy of the method used and gridding.
