ABSTRACT:
There are three different main opportunities on process improvement in industry, to obtain more profitable and sustainable results: the conceptual design phase of a new project, the optimization of an existing equipment and the troubleshooting on non-conformities. The manufactured products and industrial processes exhibit a great number of physical phenomena. Many of those phenomena closely relates to Physics of Fluids and associated solutions. That engineering technique pays attention to the correction on the cause of non-conformities due to physical phenomena but never on its effects, reaching the intimacy of such processes, avoiding tedious and expensive trials and errors procedures. The methodology employed consists on studying the physical phenomena, that govern all the fluid flow which occurs in a physical process, that operate in a market product or industrial process, regarding to one of the three opportunities of improvements. An extensive review of up-to-date data basis publications, on similar phenomena and associated mathematical model, present in advanced technologies such as Aeronautics, Space and Defense, as well as basic principles books [1 to 5] provide the scientific basis for the search on a suitable solution. The final solution takes advantage on the understanding and correction of details present in fluid flow during CFD computer simulation of the physical processes, which involves its geometric characteristics and operational condition. The following industrial sectors are using solutions provided by FEMTO: aeronautics, space, defense, appliances, energy, aluminum, oil and gas, pulp and paper, sugar and alcohol, food, petrochemical, plastics, personal products, health and glass, among many others. The present work will explore several solution examples that improved both market products and industrial processes indicating the qualitative or quantitative gain obtained using mathematical modeling and high performance CFD simulation.
