Resumen

Este trabajo tiene como objetivo calcular el rendimiento hidrodinámico de la hélice canalizada (en lo sucesivo Duct_P) en flujos oblicuos. El código numérico basado en la solución de las ecuaciones de Navier-Stokes promedio de Reynolds (RANSE) se aplica a la hélice Kaplan con conducto 19A. Para los resultados actuales se utiliza el modelo de turbulencia de transporte de esfuerzo cortante (SST) -k-ω. Los resultados hidrodinámicos de aguas abiertas se comparan con datos experimentales que muestran un acuerdo relativamente aceptable. Dos ángulos de flujo oblicuo seleccionados para analizar en este documento son 10 y 20 grados. Se presentan y discuten los resultados numéricos de la distribución de presión y el rendimiento hidrodinámico.
