Dynamic sinkage and trim
WebA finite volume method based CFD method, which takes the influence of dynamic sinkage and trim into account, is used to obtain an good prediction of the hull form resistance as well as a clear simulation of the fluid flow in the ballast channel. WebIn this study, the load fluctuation of the main engine is considered to be a disturbance for the jacket coolant temperature control system of the low-speed two-stroke main diesel engine on the ships.

WebThe stern sinkage is a combination of midship sinkage and stern-down trim, given by θ stern midships 2 L s =s + ( 6) with θ in radians. For the A3 hull at h/L =0.125, the stern sinkage reaches a maximum of around 2.8% of the waterline length just before 0Fh =1. . Note that, since the midship sinkage does not reach a maximum at exactly the ...
