CFD 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 کاملCFD Based Wing Shape Optimization Through Gradient-Based Method
1. Abstract This paper deals with the optimization of shape of aerodynamic profiles. The objective is to reduce the drag coefficient on a given airfoil while preserving the lift coefficient within acceptable ranges. A set of control points defining the geometry are passed and parameterized as a B-Spline curve. These points are modified automatically by means of CFD analysis. A given shape is de...
متن کاملEfficient Gradient-Based Shape Optimization Methodology Using InviscidlViscous CFD
In developing the automated methodologies for simulation-based optimal shape designs, their accuracy, efficiency andpracticality are the defining factors to their success. To thatend, four recent improvements to the building blocks of such amethodology, intended for more practical designoptimization, have been reported. First, in addition to apolynomial-based parameteriz...
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.
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...
