AN INVERSE DESIGN PROBLEM IN DETERMINING THE OPTIMUM SHAPE OF SPINE AND LONGITUDINAL FINS

Abstract

An inverse design problem is presented to estimate the optimum shapes for the spine and longitudinal fins by using the conjugate gradient method (CGM) based on the desired fin efficiency and fin volume. One of the advantages of using the CGM in the inverse design problem lies in that it can handle problems with a large number of unknown parameters easily and it converges very fast. Results obtained using the CGM to solve the inverse design problems are justified based on the numerical experiments.
