Resumen
En este trabajo se presenta la solución numérica-analítica para el fujo de un ferrofuido en el espacio anular entre dos cilindros concéntricos e inducido por un campo magnético rotativo. A diferencia de soluciones analíticas presentadas en la literatura, este análisis tiene en cuenta el efecto de los términos ω×M y en la ecuación de magnetización los cuales son comúnmente despreciados con el fn de desacoplar el problema magnético del hidrodinámico y entonces poder obtener una solución analítica. No obstante, se encontró que su efecto es despreciable bajo la suposición de que el vector de magnetización del ferrofuido es proporcional al vector del campo magnético. Los resultados numéricos muestran un buen ajuste con la solución asintótica reportadas por Chaves et al. 2010. También se revisa el rango de aplicación de este análisis y otros reportados en la literatura bajo la suposición de proporcionalidad de los vectores de magnetización y campo magnético.
