Mixed-Fidelity Design Optimization of Hull Form Using CFD and Potential Flow Solvers

Hull Form Optimization for Early Stage Ship Design

Shape optimization is a growing field of interest in many areas of academic research, marine design, and manufacturing. As part of the CREATE Ships Hydromechanics Product, an effort is underway to develop a computational tool set and process framework that can aid the ship designer in making informed decisions regarding the influence of the planned hull shape on its hydrodynamic characteristics...

Investigation of Temperature and Flow Fields in an Alternative Design of Industrial Cracking Furnaces Using CFD

Ship Hull Form Optimization using Artificial Bee Colony Algorithm

In this paper, artificial bee colony (ABC) algorithms are introduced to optimize ship hull forms for reduced drag. Two versions of ABC algorithm are used: one is the basic ABC algorithm, and the other is an improved artificial bee colony (IABC) algorithm. A recently developed fast flow solver based on the Neumann-Michell theory is used to evaluate the drag of the ship in the optimization proces...

Hull Form Optimization for Monohull Ships

A study was carried out to investigate methods and to determine the "optimum" hull form for monohull ships, based upon several weighted criteria. The main product of this study is a hull form optimization program. Propulsion power minimization is the primary focus of the program, although simplified. seakeeping and weight/cost issues can also be studied with the existing program. The program us...

Improving the Design of Sails Using Cfd and Optimization Algorithms

Two current Stanford Yacht Research projects are presented, both related to the analysis and design of upwind sails, and part of a larger research effort to develop efficient and robust sail and hull shape optimisation methods. First, we discuss the in-house development of a methodology to predict and improve the flying shape and forces on America's Cup sails. We adapted and parallelized a 3D u...
