Hydrodynamic forces over slender bodies can be obtained applying strip theory reducing the three dimensional hydrodynamical problem to a series of two-dimensional problems easier to solve. The slender body is divided into a …finite number of strips which can be studyed by using conformal mappings such as the Lewis two-parameter conformal mapping or the multi-parameter conformal mapping technique. These conformal mappings, transform the boundary of the submerged section of the studied body into a semi-circular boundary in the vicinity of which the hydrodynamic problem is more easily solved. One of the key aspects in the application of this technique lies in the determination of the diferent parameters that characterize the selected multiparameter conformal mapping. Typically the determination of these parameters is based on the minimization of the square of the Euclidean norm of the residue created by the selected conformal application associated to the transformation of the semi-circular boundary into the boundary of the real section of the body. One can use the Gauss—Newton algorithm, or one of its variations, to minimize the above mentioned squared Euclidean norm of the residue and thus determine the conformal mapping unknown parameters. Alternatively one can use a minimization euristic approach such as, for instance, the simulated annealing method, which is the approach followed in this work. This approach explores the annalogy between annealing in solids and multivariate optimization to approximate the global minimum of a given function. The corresponding algorithm is robust and its implementation is simple. In this work, adressing symmetric naval hull cross sections we will develop, present, test and discuss a simulated annelaling based approach to …nd arbitrary multi-parameter conformal mapping unknown parameters.
