Modification of hull design inspired by sailfish /

Abstract

Modification of hull design for improving performance and resistance in a ship has been of interest to ship building industries for decades. In the present study hydrodynamic analysis of morphological adaptations in sailfish having v-shaped protrusions on its skin has been done. The paper shall discuss a hull design integrated with v-shaped protrusions, inspired from sailfish. A quantitative analysis will be discussed with simulation proofs worked on Computational Fluid Dynamics (CFD) software. CFD results for total hydrodynamic resistance with detailed pressure distribution, velocity distribution, boundary layer separation are presented. The final result is an optimized hull form which shows interesting characteristics, as its overall resistance has de-creased in respect to a conventional hull.
