OpenFOAM Validation in Artistic Application

Computer simulation is one of the most valuable tools today because it allows reducing the cost times of a prototype, minimizing raw material and labor costs, as opposed to the characteristic trial and error required in the past. Its great boom came hand in hand with the development of personal computers and their increasing processing capacity, which has allowed an infinite possibility of creation, whose only limitation is the designer’s imagination. Another of the main attributes of the simulation lies in the increase in the effectiveness of work groups and the ease of remote work.

The purpose of most computational simulation processes, regardless of the method they use: finite differences, finite element, finite volume, spectral elements, is the discretization of the area to be studied and the evaluation of the governing equations at the nodes. For this, various commercial software focused either on the analysis of structures, fluid mechanics, heat transfer, etc. were created. Unfortunately the cost of your license can become prohibitive for small companies and startups .

It is important to highlight that in the computer simulation it is necessary to carry out a subsequent validation of the phenomena represented, to be sure that what was reported by the program really predicted the required behavior.


With the development of free environments ( opensource), simulation programs have emerged under this scheme that allow, with a little more patience, the same calculations as those with commercial licenses, being one of the most widely used for fluid and heat transfer simulation in the world the so-called OpenFOAM®. RGA ENGINEERING INTERNATIONAL, at its technological forefront, is a pioneer in Venezuela in the use of this program and began a validation project of the different turbulence models and edge conditions using OpenFOAM® with the intention of representing the random movement of confined particles of negligible weight. in a space without physical barriers, only with the use of air jets.
