El Grupo de Investigaciones Pesqueras del Instituto de Mecánica de los Fluidos e Ingeniería Ambiental (IMFIA) de la Facultad de Ingeniería en Uruguay ha desarrollado un modelo numérico que permite calcular la resistencia de los distintos componentes de un aparejo de pesca de arrastre, deduciendo las componentes que corresponden al arrastre (drag) y la sustentación (lift). Para ello, se han adoptado modelos matemáticos de todos los elementos tales como los cables de arrastre, flotadores, portones y la propia red. En este modelo numérico, la acción de las fuerzas sobre los distintos elementos modifican la configuración geométrica del conjunto con lo cual se produce un acomodamiento resistencia – geometría, reproduciendo la simulación del estado real, donde las fuerzas y la configuración convergen hacia una condición de equilibrio. Al final del trabajo, se presentan algunos resultados obtenidos en aparejos de pesca reales con datos obtenidos de sensores en pruebas de mar por medio de los cuales se pueden comparar los resultados del simulador.
