Resumen

Las metodologías numéricas han presentado una solución económica de flujos laminares y turbulentos capaz de predecir una amplia gama de dispositivos mecánicos en la ciencia y la ingeniería. En los últimos años se han empleado herramientas computacionales para analizar el comportamiento de las ecuaciones de conservación utilizadas para describir la interacción entre los flujos turbulentos y laminares utilizados para transferir la energía necesaria para operar un sistema mecánico complejo. Debido a lo anterior, este trabajo
propone la aplicación del método numérico vinculado a algoritmos matemáticos capaces de generar una solución aproximada del sistema de ecuaciones diferenciales parciales que determina los valores de presión y velocidad relacionados con el rendimiento de la bomba centrífuga en condiciones de baja Re a través del software OpenFOAM y Salome 8.3.0. Se calculó un análisis de independencia de malla para estudiar el esfuerzo computacional requerido y así establecer una descripción aproximada de los fenómenos de turbulencia producidos por la bomba centrífuga en el entorno virtual que soporta el solver MRFSimpleFoam.
