Preliminary power prediction during early design stages of a shipMoody, Robert D January 1996 (has links)
Thesis (Masters Diploma (Mechanical Engineering)) -- Cape Technikon, Cape Town,1996 / A need exists whereby the preliminary power requirement of a ship can be rapidly
estimated. Because the majority of methods available for this purpose are manual and
consist of a number of independent components, they are tedious and time consuming to
use. With the advent of the personal computer and its widespread acceptance, it was
logical to examine the various components involved to determine their suitability for
computerisation and general accuracy. In total eleven hull resistance prediction methods
were examined, eight of which were computerised. Model test data of four vessels were
used to evaluate these eight programs. The methodproviding the best results was selected
to form the core of an integrated Power Prediction program.
Factors such as appendage resistance, fouling and hull roughness were examined and
appropriate methods selected for inclusion into the integrated program.
Various propeller series were examined and evaluated against a variety of examples and
model data. Two propeller optimisation programs were written and a general method for
determining the optimum characteristics from Kr-KQ polynomials is described.
Methods for determining propulsion coefficients were examined and their results compared
with those obtained from model tests. The method providing the best overall results was
incorporated into the Power Prediction program
Added resistance due to sea state was broken down into two components, namely wind
and wave resistance. Only the head sea and wind conditions were considered. Various
methods for estimating wind resistance were examined and a program developed capable
of providing resistance estimates regardless of wind direction. The problem of added
resistance due to waves was examined and two programs written around the methods
examined. To facilitate prediction estimates, sea state was chosen as the prime function.
Wave height is estimated for the appropriate sea state and wind speed in turn from the
wave height
Actual sea trial data ofa twin screw channel ship is used to determine the overall accuracy
ofthe Power Prediction Program

Prediction of flows around ship-shaped hull sections in roll using an unsteady Navier-Stokes solverYu, Yi-Hsiang, 1976- 10 September 2012 (has links)
Ship-shaped hulls have often been found to be subject to excessive roll motions, and therefore, inhibit their use as a stable production platform. To solve the problem, bilge keels have been widely adopted as an effective and economic way to mitigate roll motions, and their effectiveness lies in their ability to damp out roll motions over a range of frequencies. In light of this, the present research focuses on roll motions of shipshaped hulls. A finite volume method based two-dimensional Navier-Stokes solver is developed and further extended into three dimensions. The present numerical scheme is implemented for modeling the flow around ship-shaped hulls in roll motions and for predicting the corresponding hydrodynamic loads. Also conducted are studies on the hydrodynamic performance of ship-shaped hull sections in prescribed roll motions and in transient decay motions. Systematic studies of the grid resolutions and the effects of free surface, hull geometries and amplitude of roll angle are performed. Predictions from the present method compare well to those of other methods, as well as to measurements from experiments. Non-linear effects, due to flow viscosity, were observed in small as well as in large roll amplitudes, particularly in the cases of hulls with sharp corners. The study also shows that it is inadequate to use a linear combination of added-mass and damping coefficients to represent the corresponding hydrodynamic loads. As a result, it also makes the calculation of the hull response in time domain inevitable. Finally, the capability of the present numerical scheme to apply to fully three-dimensional ship motion simulations is demonstrated. / text
