Resumen en español La selección de un modelo de turbulencia adecuado en la simulación de flujo de fluidos, es una interrogante frecuente en el campo del modelado computacional. Esta inquietud llevó a desarrollar este trabajo como parte de un estudio del comportamiento del flujo bifásico agua-aire en un separador centrífugo GLCC (Gas-Liquid Cylindrical Cyclone), utilizando el método del Volumen Finito. El estudio de los modelos de turbulencia se llevó a cabo, por medio de simulaciones (mas) hechas con un programa comercial, considerando flujo monofásico (Agua) en un separador centrífugo. Entre los modelos considerados están Kappa-Epsilon Estándar, Grupo Renormalizado Kappa-Epsilon (RNG) y Reynolds Stress con esquemas de interpolación de alto y bajo orden, comparándose los resultados con datos experimentales en términos de la velocidad angular medida a diferentes alturas del separador considerando diferentes caudales. Los resultados obtenidos permiten constatar que los modelos de turbulencia RNG y Reynolds Stress con esquemas de alto orden concuerdan satisfactoriamente con los datos experimentales, por el contrario, los modelos k-e y RNG con bajo orden presentan tendencias similares a las curvas experimentales pero difieren considerablemente en la magnitud de sus valores. Resumen en inglés The selection of an appropriate turbulence model is a critical step in the set up of a fluid flow simulation, as it is expected that this choice will have a significant impact on the validity of the results. In this work, we study the impact of the choice of a turbulence model, as part of a study of the behavior of air-water two-phase flow in a cylindrical cyclone separator using the finite volume method(FVM).The study was conducted with a commercial CFD code to simulate (mas) single-phase flow of water in the cyclone separator, using the standard Kappa-Epsilon (κ-ε), Renormalization-Group Kappa-Epsilon (RNG) and Reynolds Stress (RS) models with both low-order and high-order interpolation. Simulation results were compared with experimental data of angular velocities and flow rates at different heights in the separator. The results show that the RNG and RS models with high order interpolation agree satisfactorily with the experimental data, while κ-ε and low-order RNG model are able to capture the trends of the experimental data but fail to match the observed values.

Resumen en español La vía aérea ha sido propuesta como modelo de diseño óptimo desde una perspectiva física. Su diseño se ha asociado con un adecuado flujo de gases a los alvéolos, una mínima producción de entropía y un mínimo costo en materia y energía. Se ha propuesto un decrecimiento exponencial del diámetro de los bronquios (dG) en función de la generación: dG = do·2-G/3, asociado a una mínima producción de entropía. También se ha propuesto un modelo de renormalizaci (mas) ón: dG = An·G-u donde u es un exponente y An una función que introduce desviaciones periódicas en la escala, es decir más de una escala, evitando la propagación distal de errores aleatorios en el calibre de un bronquio. Sin embargo, este último resultado podría ser consecuencia en árboles asimétricos de la relación entre el diámetro y el orden del bronquio y no de la generación. En este trabajo estudiamos la asimetría y el decrecimiento del diámetro bronquial en dos especies. Se utiliza el modelo de Zamir como un sistema externo de medida de la optimización. Encontramos una clara asimetría del árbol bronquial. Comprobamos que la relación exponencial diámetro-orden es siempre muy buena (R² ³ 0,8) y que en cambio la relación exponencial diámetro-generación es menos clara (R² Resumen en inglés From a physical perspective, the air way has been proposed as a model of optimal design. Its design has been associated with a optimal gases flow to the alveoli, a minimum entropy production and minimal costs of mass and energy. The decrease of the bronchial diameter (dG) along the airway has been modeled by (i) an exponential decay of the bronchial diameter (dG) as function of its generation: dG = do·2-G/3, associated to a minimum entropy production, and (ii) a renormal (mas) ization model: dG = An·G-u where u is an exponent and An an harmonic function which introduces periodic variations in the scale, buffering the propagation of stochastic errors in the bronchial diameter. However, that the last result in asymmetric trees may be a consequence of a real relationship between diameter and order more than a relationship diameter-generation. In this work we explore this hypothesis in two species. We also use the Zamir model for vascular trees as an out method to explore the optimality degree of the bronchial ramification. We found a clear asymmetry of the analyzed bronchial trees. We shown that the relationship diameter-order is always very good (R² ³ 0,8). In contrast, the determination coefficients for the relationship diameter-generation were lower (R²
