Abstract
Se trabajó en la simulación computacional de un horno de curado de pintura para poder obtener una representación de su comportamiento y analizar posibles mejoras constructivas que permitan aumentar el desempeño. La metodología de trabajo inició con la toma de datos de temperatura y velocidad para utilizar. Se definieron puntos a considerar como entradas y salidas para la simulación computacional y ahí se tomaron las muestras. Luego de eso, se trabajó en la geometría a analizar. Para ello, se hizo una suposición de simetría longitudinal del horno. Se utilizó el software Inventor Profesional 2017 para realizar los archivos CAD de dos inyectores y dos extractores que componen los ductos internos del horno. Posteriormente, se definió la metodología de simulación. Se seleccionó el software de dinámica de fluidos computacional OpenFOAM. Se generó un dominio computacional que represente la estructura externa del horno y se posicionó el ensamblaje con los ductos en su interior.
In this project, a powder coating curing oven was investigated using computational fluid dynamics simulations. The main goal of this work, was to improve the oven performance by changing its geometry. The first step in this work was to measure the velocity and temperature. The measured data was used as boundary conditions in the simulation and to validate the computational code. A symmetrical oven geometry was designed by using software Inventor Professional 2017. The oven is composed by its internal ducts, two injectors and two extractors, and by a room where the painted objects pass through. In order to perfom the simulations, the open source OpenFOAM code was chosen. The computational domain was generated basedon the CAD files developed in the previous step.
