Turbulencia, Refinamiento de Malla Adaptativo, Simulación Numérica DirectaResumo
En este trabajo se presentan avances en el estudio numérico de la turbulencia mediante simulaciones utilizando el software Basilisk, con el objetivo de establecer una base de referencia para el análisis de modelos de turbulencia multinivel. Se trabaja sobre una simulación de flujo turbulento en condiciones periódicas, permitiendo la caracterización estadística de sus propiedades. Se utilizan técnicas de refinamiento adaptativo con el objetivo de optimizar el costo computacional sin perder resolución de las escalas relevantes del flujo. Se evalúan las fluctuaciones de las componentes de la velocidad y se calculan las correlaciones del flujo y el tensor de Reynolds. La caracterización costo-precisión de las estrategias de refinamiento en función de la precisión con la que se capturan las propiedades del flujo permite definir criterios para el modelado multinivel de flujos turbulentos.
