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 Shape Design of a Radiant Oven by the Conjugate Gradient Method and a Grid Regularization Approach

This study presents an optimization problem for shape design of a 2-D radiant enclosure with transparent medium and gray-diffuse surfaces. The aim of the design problem is to find the optimum geometry of a radiant enclosure from the knowledge of temperature and heat flux over some parts of boundary surface, namely the design surface. The solution of radiative heat transfer is based on the net r...

Flagellated actinomycetes.

Shadowed motile elements from actinomycetes were observed with an electron microscope. Included were three strains of Actinoplanes, two of Ampullariella, two of Dermatophilus, two of Spirillospora, and four of "Nocardia" turbata. In addition, three types of previously undescribed actionmycetes were represented: (i) the C(4) group (four strains) forming substrate mycelium breaking into motile ro...

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...
