COMPUTATIONAL FLUID DYNAMICS CALCULATOR FREE
Posted by Benoit Mallolīenoit holds a master's degree in Mechanical and Numerical modeling from the University of Bordeaux (France) with a specialization in CFD dedicated to free surface flows. Drag, Trim, and Sinkage comparison with experimental dataĪs the conditions of all cases are symmetric only half of the geometry is simulated.Ĭlick here for more details.In terms of output, the following will be presented: In this case, the trim and the sinkage are solved. It concerns the resistance calculation of the KCS at different speeds from 0.92 m/s to 2.38 m/s (corresponding to a variation of the Froude number from 0.1083 to 0.2816). The third case referred to case 2_2b of the Gothenburg workshop. The only difference with the previous case is the rudder which is present for the second case and not for the first. The trim and the sinkage are still blocked. it concerns the resistance calculation of the KCS while it is moving with a speed of 2.196 m/s. The second calculation referred to the cases 2_2a of the Gothenburg workshop. Axial velocity and cross-flow near the engine shaft.Wave elevation along a longitudinal section.The output of the first calculation will be: In these cases, the trim and the sinkage are blocked.
The vessel is moving with a speed of 2.196 m/s (corresponding to a Froude number of 0.26). The first case referred to case 2_1 of the 2010 Gothenburg workshop. The model contains the hull and the rudder of the KCS.
The position of the center of gravity along the X-axis has been estimated using the tool “domhydro” resulting in a location (X=-11.7, Y=0, Z=-0.115 ) in the global reference frame. The water density considered is 999.1 kg/m³. The length between perpendiculars is 7.2786 m (scale factor = 31.6) and the body draft is 0.3418 m. The computation referred to the towing tank tests performed by MOERI on the KCS.
