Abstract: The hull form optimization concerns one
of the most important applications of wave-making resistance
theories. In recent years, scholars can determine the hull form by
using the optimization method based on the computational fluid
dynamics (CFD) and other mathematical techniques. In this paper, the
hull form optimization method based on the Rankine source method and
nonlinear programming (NLP) is discussed; in the optimization
process, a hull form modification function is introduced to
represent an improved hull surface and to generate a new smooth hull
surface by changing its frame lines and bow stem profiles under the
prescribed design constraints. Numerical example is given for a
practical container hull form. Finally, shape optimization of bow
bulls is shown for non-protruding and protruding bow bulls. This
study presents a simplified and practical design method to the
select frame lines of bow bulls.
