Shape optimization towards stability in constrained hydrodynamic systems
Hydrodynamic stability plays a crucial role for many applications. Existing approaches focus on the dependence of the stability properties on control parameters such as the Reynolds or the Rayleigh number. In this paper we propose a numerical method which aims at solving shape optimization problems in the context of hydrodynamic stability. The considered approach allows to guarantee hydrodynami...
متن کاملCFD Based Shape Optimization of IC Engine
CFD Based Shape Optimization of IC Engine — Intense competition and global regulations in the automotive industry has placed unprecedented demands on the performance, efficiency, and emissions of today’s IC engines. The success or failure of a new engine design to meet these often-conflicting requirements is primarily dictated by its capability to provide minimal restriction for the inducted an...
متن کاملEvolutionary Shape Optimization in Cfd with Industrial Applications
The solution of two optimal shape design problems related to industrial CFD using genetic algorithms are considered. The first one is a single objective optimization problem, where the geometry of a flow divider of a paper machine headbox is designed subject to prescribed goals and restrictions. The second problem is a two-dimensional airfoil design problem, where the objectives are to minimize...
متن کاملConcept design and hydrodynamic optimization of an innovative SWATH USV by CFD methods
The paper presents the main characteristics of an innovative platform which has been conceived and designed to extend the operational capabilities of current unmanned surface vehicles in terms of platform stability in waves and of powering requirement at a relatively high speed. The main idea which rules the project is the realization of a small autonomous surface unit (about 6 m in length) cap...
متن کاملAutomatic shape variations for optimization and innovation - Shape Optimization of Cylinderhead Gasket using CFD
This paper presents an innovative tool and method that allow efficient innovation of shape and topology of virtual parts at both mesh and CAD levels using optimization methods. The method consists of automatic variations of shapes in CAD/CAE environments that allow effective search for new shapes that are not considered initially by designers.
