Optimum Shape and Design of Cooling Towers

The aim of the current study is to develop a numerical tool that is capable of achieving an optimum shape and design of hyperbolic cooling towers based on coupling a non-linear finite element model developed in-house and a genetic algorithm optimization technique. The objective function is set to be the minimum weight of the tower. The geometric modeling of the tower is represented by means of ...

Optimum Design Program for Shape of Arch Dams

This paper presents an applicable and practical computer program(ODPSAD) and suggests a new algorithm for geometry of concrete arch dams. In this program shape optimization of arch dams for static and dynamic loads and enhancement of its seismic behaviour is carried out. abutment excavation and dam body volumes have been considered as the objective function and in order to increase the consiste...

Automatic shape independent clustering with global optimum cluster determinations

A new method which allows identifying any shape of cluster patterns in case of numerical clustering is proposed. The method is based on the iterative clustering construction utilizing a nearest neighbor distance between clusters to merge. The method differs from other techniques of which the cluster density is determined based on calculating the variance factors. The cluster density proposed he...

On the Optimum Die Shape in Rod Drawing Process Considering Work-Hardening Effect of Material

The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...
