Modelos Matemáticos para el Régimen No Permanente en Canales de Riego [Spanish]

Book Format

Number of Pages

Publisher

<p>En este trabajo se analiza un modelo matemático de flujo no permanente en canales de riego para varios tramos, considerando las estructuras de control que le sirven de condición de frontera entre los diferentes tramos, ya sean externas o internas, y que son las que originan que se presente este tipo de flujo. Se utiliza un esquema de diferencias finitas implícito, con una adecuación del esquema de Preissmann, considerando la presencia de flujos laterales, para aproximar la solución de las ecuaciones de Saint Venant, se usaron expresiones matemáticas que representan este tipo de flujo en escurrimientos a superficie libre; para lo cual se desarrolló un programa para simular el flujo en el canal y otro para calibrar el modelo. Se determinaron y analizaron los modelos matemáticos de flujo impermanente en estructuras de control en canales, específicamente: compuertas y vertedores. Se realizó la calibración, verificación y validación de los modelos, en instalaciones de laboratorios de hidráulica, de Cuba y México, así mismo se valido el modelo en el canal principal del distrito de riego de San Juan del Río, México.</p><br/><p>El autor es doctor en Ingeniería Hidráulica, así como Profesor Investigador de la Universidad Autónoma Chapingo, el presente libro conforma la tesis de grado obtenido en el Centro de Investigaciones Hidráulicas de La Habana, Cuba, y cuyo tutor fue el Dr. Alcides León Méndez.Ha impartido diferentes cursos de Hidráulica, e infraestructura Hidráulica.</p>
